Panic Crash
I put my iMac Pro in sleep mode last night (this is my typical end-of-day routine). I came in this morning to my startup screen. Once it booted into my user account, I found a crash report. The top line reads:
Panic(CPU 0, time 720469129135130): NMIPI for unresponsive processor: TLB flush timeout, TLB state:0x0
RAX: 0x0000000000003058, RBX: 0xffffff8b74918000, RCX: 0x0000000000020000, RDX: 0x0000000000020000
