Bug 840942 – Significant regression in sys-kernel/gentoo-kernel{,-bin}-{5.17.[34],5.16.20,5.15.34,5.10.111}

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Daniel Harding 2022-04-26 06:40:03 UTC]

Upstream kernel commit 5467801f1fcbdc46bc7298a84dbf3ca1ff2a7320 causes a severe regression on certain laptop models.  When the affected systems are suspended, they essentially become bricked.  On my laptop, a Dell Inspiron 5515, the only way to recover was to open up the case, disconnect the internal battery, and hold down the power button.

The broken commit was backported to the following stable trees:

5.17.3 (also present in 5.17.4)
5.16.20
5.15.34
5.10.111

LKML discussion:  https://lore.kernel.org/lkml/[e-mail]/

The fix has been applied to mainline by Linus, but it is not yet in any stable releases:  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/gpio?id=06fb4ecfeac7e00d6704fa5ed19299f2fefb3cc9

I don't know how prevalent the affected systems are, but because of the severity of the problem for the ones that are affected, I wonder if it would be worth masking the affected kernel versions (or possibly rev-bumping them with the patch that fixes the issue).

[Comment 1 Michał Górny 2022-04-26 06:51:16 UTC]

I'll mask them, just please give me a minute to verify affected versions.

Just a note that the fix commit is already queued up for the next stable release train, which should arrive sometime this week.

[Comment 6 Michał Górny 2022-04-26 16:05:47 UTC]

I've pushed revbumps for sys-kernel/gentoo-kernel* and removed broken versions.  Let's wait for upstream release with (unsupported) sys-kernel/vanilla-kernel, and then close the bug.

Did commit 81c34c59b actually fix this for 5.15.35? The contents of genpatches-5.15-39 are same as those of genpatches-5.15-38.

Sorry for the noise, just saw the #2800 in genpatches-5.15-39.base .

[Comment 9 Michał Górny 2022-04-27 17:08:05 UTC]

All kernels bumped and buggy versions removed.
