Description

Proposed as a Blocker for 42-final by Fedora user eischmann using the blocker tracking app because: Because of this Fedora 42 doesn't even boot for me. It is a regression from Fedora 41. Adam Williamson also reported this to me by email. This is fallout from Fedora moving to gcc 15 pretty aggressively and the combination of gcc 15 and the driver for the ivsc chip found in various Dell laptops is causing this crash. I have just reproduced this by moving to F42 / gcc 15 for building my local test kernels. I'm working on a fix now. I've a fix for this now and submitted it upstream + downstream: https://lore.kernel.org/lkml/20250318141203.94342-1-hdegoede@redhat.com/ https://gitlab.com/cki-project/kernel-ark/-/merge_requests/3741 (rawhide) https://gitlab.com/cki-project/kernel-ark/-/merge_requests/3742 (fedora 42 can be worked around with kernel arg: module_blacklist=ivsc_cei,ivsc_ace,mei_vsc,mei_vsc_hw probably it's not necessary to block *all* of them, but hey, it does the job. it does seem to stop the camera working, though. I'll write this up with a bit more detail in the commonbug later. Discussed during the 2025-03-24 blocker review meeting [1]: * AGREED: 2353148 - punt (delay decision) on blocker status, AcceptedFreezeException (Final) - the vote on blocker status for this is split, but there is clear consensus for a freeze exception. As the fix for this is already lined up, we expect it will land before deciding the blocker status becomes crucial [1] https://meetbot.fedoraproject.org/blocker-review_matrix_fedoraproject-org/2025-03-24/f42-blocker-review.2025-03-24-16.02.log.html Fix is already in Rawhide kernel and should be in next F42 kernel I believe. It looks to me like https://bodhi.fedoraproject.org/updates/FEDORA-2025-254062023c should have fixed this, it's in the changelog. I'll test it on my affected system shortly. If other affected folks can test too, that'd be great. can confirm this works on my XPS 13. I have that kernel booted with the blocklist removed so the vsc modules load, the kernel booted fine, the webcam works (not well, but it works). Will set VERIFIED and close soon unless anyone else reports they still have issues. ok, nobody yelled, so I'm closing it. |
