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).
