Xserver shutting down unexpectedly

[Sylvain Archenault]

Hello,

Since the kernel 5.10.0-8, it seems that my xserver is stopping
unexpectedly, here's the last couple of lines of Xorg.0.log:

[  1938.884] (II) systemd-logind: releasing fd for 13:65
[  1947.134] c000:5191: 00 ILLEGAL EXTENDED X86 OPCODE!
[  1947.134] c000:5191: 00 ILLEGAL EXTENDED X86 OPCODE!

[  1947.135] (WW) xf86CloseConsole: VT_ACTIVATE failed: Input/output error
[  1947.136] (II) Server terminated successfully (0). Closing log file.

Some other times, it seems i only get this:
[    40.943] (II) systemd-logind: releasing fd for 13:65
[    40.990] (II) NVIDIA(GPU-0): Deleting GPU-0
[    40.991] (II) Server terminated successfully (0). Closing log file.

My graphic card is: NVIDIA Corporation GM206GL [Quadro M2000]

On 5.10.0-8, it seems to affect 460.73-1 and 470.42.01. The system seems
stable on 5.10.0-7 and 460.73-1.

Does anybody experience the same thing? I could not find anything else
interesting in the logs, but maybe i'm not looking in the right place...

Thank you
Sylvain
