Created attachment 306839 [details] Lenovo P50 system information Running several Lenovo P50 we've noticed failure on suspend after updating to kernel version 6.8.0-40 Systems don't wake up once suspend is reached while LEDs FnLk and Numlk stay on at this state. /var/log/syslog: 2024-09-03T15:32:40.130401+02:00 p50benni systemd[1]: Reached target sleep.target - Sleep. 2024-09-03T15:32:40.140701+02:00 p50benni systemd[1]: Starting systemd-suspend.service - System Suspend... ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^ Only after hard reset (power off switch) computer can be used again. When booting last kernel-version 6.5.0-45 via GRUB, suspend works flawless again. To confirm, we've tested live-systems on three different Lenovo P50: Kubuntu 24.04.1 LTS und Linux Mint 22, both come with 6.8 Kernel. In all three tests the suspend-problem occurs so a bug seems to be very likely. Information on the system environment / hardware is in the attachment. Hope this all helps... kind regards, Sascha.
Vendor kernels aren't really supported here. Please try vanilla 6.10.9 or 6.11-rc7.
I'd happily provide more data if anybody would point me to which data is needed. We have several P50 machines in our business so we're really interested in helping solve this. Unfortunately my skills are advanced linux user, far from being Guru. Am 10.09.24 um 13:14 schrieb bugzilla-daemon@kernel.org: > https://bugzilla.kernel.org/show_bug.cgi?id=219253 > > Artem S.
