Description Mark Pearson 2025-08-12 18:18:39 UTC
1. Please describe the problem:
During Linux enablement on our Lunarlake platforms (especially the X9-14 and X9-15) we were seeing rare crashes during suspend and resume.
This was tracked down to being an issue in the Intel THC driver and a fix has been posted and accepted into the maintainers branch.
Not sure if it would automatically make it's way into Fedora 6.16 so submitting a MR to get it pulled in quicker. This bug is for tracking :)

Upstream patches: https://patchwork.kernel.org/project/linux-input/patch/20250803065726.2895470-1-aaron.ma@canonical.com/

2. What is the Version-Release number of the kernel:
6.16

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
New issue

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Hard to reproduce, but we have been able to do so in our QA lab

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Didn't check

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
See upstream patch for failure logs

Reproducible: Always
