Public bug reported: Since upgrading to Ubuntu 21.10, my computer sometimes fails to properly wake from suspend. It does start running again, but there is no video output. I'm attaching text for two crashes from kernel log output. First is: /var/lib/dkms/nvidia/470.63.01/build/nvidia/nv.c:3967 nv_restore_user_channels+0xce/0xe0 [nvidia] Second is: /var/lib/dkms/nvidia/470.63.01/build/nvidia/nv.c:4162 nv_set_system_power_state+0x2c8/0x3d0 [nvidia]
Apparently I'm not the only one having this problem with 470 drivers. https://forums.linuxmint.com/viewtopic.php?t=354445 https://forums.developer.nvidia.com/t/fixed-suspend-resume-issues-with-the-driver-version-470/187150 Driver 470 uses the new suspend mechanism via /usr/lib/systemd/system- sleep/nvidia. But I was using that mechanism with driver 460 in Ubuntu 21.04 and sleep was reliable then. Right now I'm going back to driver 460.
