[9fans] SMC SYS-5018A-FTN4 lapic weirdness (9front)

2019-04-17 Thread Lyndon Nerenberg
I have a stack of Supermicro SYS-5018A-FTN4 servers upon which I'm trying to spin up 9front. For the most part they work, but one annoyance is the *endless* stream of cpu0: lapicerror: 0x0080 messages the kernel prints out. Sometimes these originate from cpu1 as well. The hardware has ei
