Hello,

Since kernel 6.3.1 (last update) the boot process hangs (~ 5 seconds) by uevent triggering with the following errors :

logitech-hidpp-device 0003:046D:405E.0004: hidpp_devicenametype_get_count: received protocol error 0x07

Steps to reproduce:

Just boot and wait.

Next, once booted and remove the unify receiver and plug it again there is a massive lag (~ 1 minute) before that the receiver get ready for the mouse and keyboard to be functional with following errors :

kernel: logitech-hidpp-device 0003:046D:405E.0022: hidpp_devicenametype_get_count: received protocol error 0x07
kernel: logitech-hidpp-device 0003:046D:405E.0023: Couldn't get wheel multiplier (error -110)

Unify receiver with K800 keyboard and M720 Triathlon mouse paired.

The strange thing is that this happen on my desktop computer but no problem on my laptop with a unify receiver and a marathon 705 mouse.

On the desktop the boot is fine without the unify receiver.

Let me know if you need more info.

Thank you.

This appears to be a kernel regression. The general advice to debug kernel regressions is here [1]. You might have to report it upstream, either to the kernel bugzilla or possibly the linux-input mailing list [2]. Please let us know what you find out.

@Guy B, I have this bug as well since 6.3.1. Where was it suggested to you to raise this as a systemd bug? I don't see it in https://bugzilla.kernel.org/show_bug.cgi?id=217412.
Comment by Guy B (sushi2503) - Monday, 08 May 2023, 07:01 GMT
@ Mark Blakeney, because of the Artem S. Tashkinov's answer : "I can imagine not a lot of people have your HW and run 6.3.1". What does that mean ? As far as I already can see, I'm not the only one.

In the given link from bugzilla.kernel.org (https://docs.kernel.org/admin-guide/bug-bisect.html) they say :

Devices not appearing

Often this is caused by udev/systemd. Check that first before blaming it on the kernel.

That's the reason why.

I can confirm the issue since 6.3.1, made my boot time increase by 17 seconds
Comment by Ali Molaei (ali_molaei) - Friday, 12 May 2023, 12:45 GMT
Looks like the issue has been resolved in 6.4-rc1

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/diff/drivers/hid/hid-logitech-hidpp.c?id=v6.4-rc1&id2=v6.3

I can confirm installing linux-mainline 6.4rc1-1 on ArchLinux that the issue has been resolved

Kernel 6.3.2 worse then 6.3.1, more lag at boot.
Comment by loqs (loqs) - Tuesday, 16 May 2023, 19:40 GMT
@sushi2503 are the two kernels from [1] affected?

@loqs : Is that the link to the headers (because they are both marked as linux) ? https://drive.google.com/file/d/1vBRnTD … share_link linux-6.2.r5715.g0175ec3a28c6-1-x86_64.pkg.tar.zst

But the second links are marked as linux-6.2rc6.r1261.g60b07cf5d346-1-x86_64.pkg.tar.zst and linux-headers-6.2rc6.r1261.g60b07cf5d346-1-x86_64.pkg.tar.zst

I need the headers for the first links to test and confirm.

Oops. Fixed link references now.

@loqs : The two kernel from [1] are not affected. No boot lag and no problem by unplugging/plugging the receiver in the session.

@loqs, linux-6.2.r6328.g6861eaf79155 is bad.

BTW, anybody with a Logitech mouse using a USB receiver dongle, i.e. https://www.logitech.com/en-au/products/mice/unifying-receiver-usb.910-005934.html (which I would think is about every second PC user on the planet) just needs to plug the receiver out then in and you will see the mouse stays dead for about 20 secs. On a good kernel it works immediately.

Tested the linux-6.3.2.arch1-1.1-x86_64.pkg.tar.zst & linux-headers-6.3.2.arch1-1.1-x86_64.pkg.tar.zst and it's ok. But I still have the filling that there is a small delay at boot (unplugging/plugging the receiver during the session is perfect) :

mai 17 17:42:36 Cockpit kernel: logitech-hidpp-device 0003:046D:2010.0005: HID++ 1.0 device connected.

mai 17 17:42:39 Cockpit systemd-tty-ask-password-agent[430]: Password query on /dev/tty1 finished successfully.
mai 17 17:42:39 Cockpit systemd-cryptsetup[411]: Set cipher aes, mode xts-plain64, key size 512 bits for device /dev/disk/by-uuid/********

Which is also the case with the linux-6.2rc6.r1261.g60b07cf5d346-1-x86_64.pkg.tar.zst & linux-headers-6.2rc6.r1261.g60b07cf5d346-1-x86_64.pkg.tar.zst.

But completely flawlessly with linux-6.2.r5715.g0175ec3a28c6-1-x86_64.pkg.tar.zst & linux-headers-6.2.r5715.g0175ec3a28c6-1-x86_64.pkg.tar.zst which has the same behavior as kernel 6.2.13 (the last working one).

If someone else could confirm.

A "detail" : By non working kernels in xfce desktop > parameters > mouse/keyboard the name of the devices are not listed (example logitech K800) but the device id (0003:046D:2010.0005).

Comment by Guy B (sushi2503) - Wednesday, 17 May 2023, 18:47 GMT
Yes, just tested linux-6.2.r6153.g241ed6ab74f9-1-x86_64.pkg.tar.zst & linux-headers-6.2.r6153.g241ed6ab74f9-1-x86_64.pkg.tar.zst, very bad, about ~ 10 seconds lag at boot time (uevent triggering) but no problem by unplugging/plugging the receiver during the session. And the devices are not listed as (example logitech K800) but by the device id (0003:046D:2010.0005).

I'm going back to linux-6.2.r5715.g0175ec3a28c6-1-x86_64.pkg.tar.zst & linux-headers-6.2.r5715.g0175ec3a28c6-1-x86_64.pkg.tar.zst to confirm the "flawlessly" for tomorrow cold boot.

Let me know if you want to test your last edits (Edit & Edit2) :

linux-6.2rc7.r105.ga738688177dc-1-x86_64.pkg.tar.zst & linux-headers-6.2rc7.r105.ga738688177dc-1-x86_64.pkg.tar.zst

For me the second best after linux-6.2.r5715.g0175ec3a28c6-1-x86_64.pkg.tar.zst in which there is no doubt.

@loqs, your kernel linux-6.3.3.arch1-1.2 is not the repo linux-6.3.3.arch1-1 right ? Because the Arch repo linux-6.3.3.arch1-1 is still buggy.

No I changed the pkgver to 1.2 so you can tell it apart. It contains https://lore.kernel.org/all/CAHk-%3DwhvhkSk6m8_AidhofgR9nq0Md%2BHbNad5r1RE69tZgbv6Q%40mail.gmail.com/

I'm surprised that today's 6.3.5.arch1-1 still has this annoying bug.

@loqs, note that bug comment description, and the patch, say it is to fix "overly long boot times" whereas my experience of the bug is merely to replug my logitech mouse receiver and see it takes about 15 secs to reconnect. The OP describes that here also. There is no delay on previous working kernels (e.g. linux-lts which I am using until this bug gets fixed). Anyhow, I tested your last linux-6.3.5.arch1-1.1 and it still has the receiver delay bug.

@bulletmark just to confirm reverting 586e8fede7953b1695b5ccc6112eff9b052e79ac resolves the issue for you? Such as linux-6.3.2.arch1-1.1-x86_64.pkg.tar.zst above.

@loqs, I am pretty sure I have tried every one of your test kernels and none resolve the issue. Give me a direct link to that kernel and I will try again to confirm.

@loqs, that kernel does fix the problem.

I also reverted 586e8fede7953b1695b5ccc6112eff9b052e79ac from the current Arch kernel 6.3.5.arch1-1 to confirm again the problem is fixed.

@loqs : Tested linux-6.3.5.arch1-1.1 not working, the unplug/plug receiver hangs.

linux-6.3.2.arch1-1.1 working perfectly, no boot hang and no unplug/plug receiver hang.

Please confirm that the linux-6.3.2.arch1-1.1 reverted to 586e8fede7953b1695b5ccc6112eff9b052e79ac so I can confirm on kernel bugzilla.

Correct linux-6.3.2.arch1-1.1 reverted 586e8fede7953b1695b5ccc6112eff9b052e79ac.

@loqs : Thanks, reported on kernel bugzilla.

Is the fix you already tested in linux-6.3.5.arch1-1.1-x86_64.pkg.tar.zst and reported did not fix the issue.
Comment by Guy B (sushi2503) - Saturday, 03 June 2023, 06:28 GMT
@loqs : Right, the linux-6.3.5.arch1-1.1-x86_64.pkg.tar.zst didn't fix the issue as well as for Mark Blakeney but the linux-6.3.2.arch1-1.1 did.
So, now I'm not sure if on kernel bugzilla they understand it ?

Edit : I reported (on kernel bugzilla) that this patch doesn't fix the problem but your modified linux-6.3.2.arch1-1.1 did. I hope that there will not be any confusion about.

New bug report opened as suggested by the The Linux kernel's regression tracker (Thorsten Leemhuis) (it sounds like they are two different bugs there) here :

https://bugzilla.kernel.org/show_bug.cgi?id=217523

@Mark Blakeney (bulletmark) : Would be good to confirm your observations about not working patched 6.3.5.arch1-1 on the new bug report.

@loqs : Is your linux-6.3.6.arch1-1.3-x86_64.pkg.tar.zst link the official Archlinux last kernel update or one to test ?
Comment by loqs (loqs) - Tuesday, 06 June 2023, 20:41 GMT
linux-6.3.6.arch1-1.3-x86_64.pkg.tar.zst is the one to test. The official release is linux-6.3.6.arch1-1-x86_64.pkg.tar.zst without the additional .3 in the pkgver.
Comment by Guy B (sushi2503) - Tuesday, 06 June 2023, 21:01 GMT
Tested right now and I can confirm that your linux-6.3.6.arch1-1.3-x86_64.pkg.tar.zst is again working flawlessly (for me), no boot delay and no hang by unplug/plug the unify receiver.

Thanks a lot loqs.
Comment by Mark Blakeney (bulletmark) - Tuesday, 06 June 2023, 22:40 GMT
@loqs, I also confirm your 6.3.6-arch1-1.3 kernel fixes the delay issue. You know this stuff well. Will those 2 patches make it to 6.3, or will we have to wait until 6.4?

Hey @loqs, another awesome support effort on this one! Thanks for all your work :)
