Public bug reported: Dear Ubuntu dev teams,
A detailed description of the problem I faced is here : https://askubuntu.com/questions/1562988/ubuntu-24-04-lts-frequent- system-freeze-crashes-since-1-week-related-to- the?noredirect=1#comment2749977_1562988 I use an embedded GPU in an AMD A8-7650k. Since the release of the latest HWE in January, the system became completely unusable (several crashes per hour), I had to rollback to a fresh system based on the 24.04.3 / 6.14.0-37. I immediately high ly suspected the graphic part to be the root cause. The only relevant information I could get is those logs : journalctl -p err -b -1 janv. 18 12:06:50 surya-Audace systemd-udevd[443]: /usr/lib/udev/rules.d/90-alsa-restore.rules:18 GOTO="alsa_restore_std" has no matching label, ignoring. janv. 18 12:06:50 surya-Audace systemd-udevd[443]: /usr/lib/udev/rules.d/90-alsa-restore.rules:22 GOTO="alsa_restore_std" has no matching label, ignoring. janv. 18 12:06:51 surya-Audace kernel: UBSAN: array-index-out-of-bounds in /build/linux-fRGTtX/linux-6.17.0/drivers/gpu/drm/radeon/radeon_atombios.c:2720:34 janv. 18 12:06:51 surya-Audace kernel: index 16 is out of range for type 'UCHAR [*]' janv. 18 12:06:51 surya-Audace kernel: UBSAN: array-index-out-of-bounds in /build/linux-fRGTtX/linux-6.17.0/drivers/gpu/drm/radeon/kv_dpm.c:2508:32 janv. 18 12:06:51 surya-Audace kernel: index 48 is out of range for type 'UCHAR [*]' As I had to rollback to a previous kernel, I can't dig anymore into this issue to collect new technical informations, would this be enough to inspect what has changed in the code ?
