Arch Linux

Same here with blank screen.

Please work through the support channels to determine the exact cause of the bug. See also [1] for advice on debugging kernel regressions.

[1]: https://wiki.archlinux.org/title/Kernel#Debugging_regressions

As pointed out by @loqs, definitely seems like an upstream kernel regression. Some noteworthy lines from your log below. i915 driver kernel issues can be reported upstream at [1]. But as indicated, probably best if you first of all visit the Arch support channels for troubleshooting assistance. Please let us know what you find out.

Tracked here : https://gitlab.freedesktop.org/drm/intel/-/issues/9636

Thanks for clarifying the information. On bugzilla, the status is now RESOLVED CODE_FIX, so I tried installing the linux-mainline 6.7rc1 package and the regression was resolved.

@Nebulosa does [1] fix the issue for you? Which is a test fix from [2].

[1]: https://gitlab.freedesktop.org/drm/intel/uploads/fcccbfe2833d6f4679dff3608c735ee2/0001-drm-i915-Also-check-for-VGA-converter-in-eDP-probe.patch

Recheck OS working on 6.7.0-rc1-1-mainline and regression I still here. I'm apologizing for misleading.

Downgraded kernel again on 6.5.9.

@Nebulosa if the issue is building a patched kernel to test, the kernel linked below is 6.6.1-arch1 with [1] applied:

Thank you for participating! Building is not an issue, it just takes a long time (about 12 hours on my laptop).

So, I took PKGBUILD from: https://archlinux.org/packages/core/x86_64/linux/, added patch 0001-drm-i915-Also-check-for-VGA-converter-in-eDP-probe.patch, made sure that the changes were applied and installed the linux, linux-headers packages (version 6.6.1-arch1-2 in my case). Regression is still here. Dmesg: https://0x0.st/Hvjp.txt

Also, I tried to install your packages '6.6.1.arch1-1.2' but nothing changed. Dmesg: https://0x0.st/Hvjx.txt

6.5.9 is still the latest kernel that worked.

@Nebulosa were you able to bisect the kernel or confirm if 49d4648b65d03752904ac945aefa60044329a9a3 was the first bad commit as in 9636 [1]? If it is not 9636 then the issue still needs reporting upstream?

[1] https://gitlab.freedesktop.org/drm/intel/-/issues/9636

Can't understand how I can confirm is bad commit or not without of full procedure of bisecting?

Meanwhile, I read wiki, forum, etc., installed ccache and modprobed-db, removed docs building from PKGBUILD and started procedure of bisecting.

> Can't understand how I can confirm is bad commit on not without of full procedure of bisecting?
If you are checking out the commits and using makepkg -e:
git checkout 49d4648b65d03752904ac945aefa60044329a9a3 # test if the commit is bad
git show 49d4648b65d03752904ac945aefa60044329a9a3 # confirm the commit is not a merge
git rev-parse 49d4648b65d03752904ac945aefa60044329a9a3~ # get the commits first parent
git checkout 9856308c94ca821fdc6f3440e4d4de069b09677c # test if parent of the commit above is good

Yes, I'm using this article https://wiki.archlinux.org/title/Bisecting_bugs_with_Git and https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git -for sources

After git checkout, I should build kernel again, right?

Yes:
$ cd ../..
$ makepkg -efsi

Finally I get the answer, both of commit - Kernel panic or blank screen with blinking cursor.

Continue bisection proccess...

@chromer030 do you want to open a separate bug report for the issue you bisected asking for the inclusion of [1]?

[1]: https://cgit.freedesktop.org/drm-intel/commit/?h=for-linux-next&id=fcd479a79120bf0cd507d85f898297a3b868dda6

I've done bisect.

https://github.com/torvalds/linux/commit/0d16710146a10cf62b3efddee8ffd006432d5d7e - is first bad commit

What should I do next?

As a cross check try 6.6 or 6.6.2 or 6.6.2.arch1-1 or 6.7-rc2 with 0d16710146a10cf62b3efddee8ffd006432d5d7e reverted.
Assuming you can no longer produce the issue with the revert you need to decide if you want to report the issue against the i915 driver [1] or acpi [2] possibly on the https://bugzilla.kernel.org product ACPI component ACPICA-Core and add to the CC list Michal Wilczynski <michal.wilczynski@intel.com> plus Rafael J. Wysocki <rafael.j.wysocki@intel.com> or the linux-acpi mailing list possibly by replying to https://lore.kernel.org/linux-acpi/20230703080252.2899090-3-michal.wilczynski%40intel.com/

Yep, reverting commit helps, 6.7rc2 works fine.

Trivial patch in attach.

I think it's i915-specific bug, on my other instances (with Nvidia card or with other several vpses with virtual cards) there is no regression at all, so right decision will be reporting issue in gitlab.freedesktop org at first.
