@bsmojver Could you try thesofproject/linux#5930?
bsmojver commentedon Sep 27, 2026
I just asked Fedora maintainer to roll an update with this commit included. I'll keep you posted.
mrhpearson commentedon Sep 28, 2026
Just a note that I can repro the issue on my system too. Kernel build is running and will update once tested.
mrhpearson commentedon Sep 28, 2026
Confirmed that the sofproject 7.3.0-rc3+ kernel build worked and I don't get the out of bounds exception.
I guess I should confirm that the single commit on the Fedora kernel is needed next. Will trigger another kernel build shortly
mrhpearson commentedon Sep 29, 2026
Confirmed just that patch on the Fedora 7.2 kernel fixes the problem.
Submitted MR for Fedora kernel to pick up the fix: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/4765
(though I just noticed it was tagged for stable so I probably didn't need to)
