Upgrading to 5.4.0-39-generic kernel causes GPU to crash shortly after logging in

[Leon Matthews]

I upgraded my kids' computer to the 5.4.0-39-generic kernel today. Afterwards, the screen started freezing very shortly after logging in.

When choosing the older 5.4.0-37-generic from the grub menu I see no crashes at all.

I could login over SSH from my computer without difficulty. Running dmesg showed some variation of the following. For example, just now it crashed when my daughter tried to launch Firefox after logging in, and the following appeared while I was watching the output of 'dmesg -w':

68.824967] NVRM: GPU at PCI:0000:01:00: GPU-7f44f739-3c25-c282-d7a3-c4ec7c79e755

The system has been running beautifully up until today. Installing the other driver versions listed below didn't help any.

Hmm, there aren't many change between -37 and -39. Can you please attach dmesg under -39?

[Kai-Heng Feng (kaihengfeng)]

should be -37...
