Let me make sure I understand it correctly: you had "idle=nomwait" on
the kernel command line and it became unresponsive?

If so, it would be really helpful if you could connect that box over
serial to another one and collect logs in realtime with the hope of
maybe catching something relevant.

The other thing I could suggest is to disable SMT: I know of another
threadripper machine where disabling SMT helped with the lockups. (Not
saying this is the final solution but it would be a good data point to
know).

Thx.
