Title:
kernel bug 6.8.0-11 Ubuntu 24.04 with MT7921
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu Noble Numbat (development branch) x86_64
The problem is this: there is an error with the Wi-Fi driver MT7921
[ 825.412953] mt7921e 0000:04:00.0: Message 00020007 (seq 8) timeout
[ 825.413273] mt7921e 0000:04:00.0: PM: dpm_run_callback(): pci_pm_resume+0x0/0x110 returns -110
[ 825.413296] mt7921e 0000:04:00.0: PM: failed to resume async: error -110
And I found a ready-made patch for it that solves the problem
https://github.com/ShadowBlip/rz608-fix
And after this simple script the problem disappears
I'll attach the logs before and after I made this patch.
Add this solution to your distribution. Better yet, contact the people who are responsible for the kernel and add it there so that it is global and applies to all distributions, because I noticed the same thing in Fedora.
