I have Thinkpad P16 and it freezes after some time, or some action after wakeup from hibernate (external displays and mouse&keyboard plugged in Thunderbolt). I mean, mouse still moves and I can ssh to the machine and this is the stack trace I found through dmesg (nothing more in syslog). If I run nvidia-smi, the command freezes - it doesn't output anything.

System information:
- xubuntu 22.10
- kernel: 5.19.0-29-generic
I also updated all of the firmware to the latest version (with fwupdmgr update). Is there anything else I can do to make hibernate work? Perhaps with different driver for Nvidia graphics?
Best regards.
