Hi,

Kernel: 5.14.1.arch1-1
Hardware: RME HDSPe Multiface II (snd_hdsp module)

With 5.14.1 in testing just launching alsamixer causes the panic that I put in attachment, in snd_dma_buffer_mmap.

Also, my USB devices keep restarting and sometimes just don't work when rebooting, e.g. I had to unplug / replug my USB keyboard a few times before being able to type and even then, dmesg fills up with "restarting SuperSpeed USB device number <...> using xhci_hcd" messages. Some audio software are able to launch but then get stuck upon exit (even with kill -9, I have to reboot the machine with the hardware button to be able to reboot). So maybe there's some deeper memory corruption.
This task depends upon

Hi,

Kernel: 5.14.1 to 6.arch1-1
Hardware. RME HDSP 9632

I'm affected too by a kernel oops about snd_dma_buffer_mmap.

If I launch a media player like Deadbeef or mpv it freez the player not the all computer and the only way to get sound back is to revert to kernel 5.13.13.arch1-1.

Sorry if I posted at the wrong place (it's my first report) but it looks like the same problem.

I was advised to post here by a reply from Deadbeef player bug report :

https://github.com/DeaDBeeF-Player/deadbeef/issues/2674

Let me know if you need more info.

Thanks.

Could you try a kernel with this patch applied? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=cbea6e5a7772b7a5b80baa8f98fd77853487fd2a

Sorry but I never patched a kernel myself. I'm reading about but sounds not that easy for me.
Comment by Jan Alexander Steffens (heftig) - Monday, 20 September 2021, 20:02 GMT
Please try the kernel in https://pkgbuild.com/~heftig/linux-with-cbea6e5a7772/

The log is a bit shorter but it still freezes mpv and Deadbeef.

A side effect of the bug is that it freezes one of my conky too!?

P.S. As info, I just installed the kernel not the headers.

Please file a kernel bug if you haven't already; see https://www.alsa-project.org/wiki/Bug_Tracking (don't forget the mentioned alsa-info.sh https://www.alsa-project.org/wiki/AlsaInfo ).

Ah, I will have one more kernel to try before you do that.

BINGO !

It's working again flawlessly with that kernel. I have tried with both player (Deadbeef & mpv) and firefox (youtube) too.

Thank you very much.

P.S. Will this modifications added to the main Arch kernels soon ?
