Public bug reported:
Hello,
I'm experiencing frequent crashes that hard-lock the system and kernel
completely.
Symptoms are:
- Frozen screen
- No Keyboard or Mouse input accepted
- Remote SSH times out as if system is not responding
- Kernel does not respond to the "Alt + SysRq + REISUB" key sequence to force a
reboot. (kernel was compiled with CONFIG_MAGIC_SYSRQ=y)
I tracked down the issue to the nouveau driver (see attached journalctl
logs for crash dump)
The primary and only PCI Video card in the system is quite old and thus
should be well supported:
- 01:00.0 VGA compatible controller: NVIDIA Corporation GT215 [GeForce
GT 240] (rev a2)
lshw output:
