I have RTX 3060 on Debian 12, VFIO binds fine, Windows 10 VM boots, benchmarks run perfect. But when I launch real game, host dies in 5-10 minutes. No logs, no panic, just black screen and reset button.
Is very strange because mining works 24h no problem. Only gaming kills it. ¿Someone see this before?
Specs:
Jajaja I know, mining rig do gaming, living the dream. But please help.

Classic IRQ conflict. Just use a proper kernel. Skill issue.
Your B550 is probably sharing lanes between the x16 slot and the M.2. Check
lspci -vv | grep -i "interrupt:" and look for duplicates. Gaming load spikes interrupts. Mining is steady-state, doesn't trigger the race condition.
Also: "living the dream" yes, but the dream includes debugging ACPI tables at 2AM.
oops: 0000 [#1] SMP

WRONG.
It is the PSU.
Gaming spikes watts.
Mining is steady.
Your 500W unit is DYING.
Buy proper hardware.
Arguing with myself: no it is not PSU he said mining runs fine
STILL WRONG. MINING USES DIFFERENT PART OF GPU!
