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: 0x00000080 messages the kernel prints out. Sometimes these originate from cpu1 as well. The hardware has eight CPU cores. I don't think I've seen anything from cpu>1, but in the blizzard of messages, who knows. I poked a wee bit inside the kernel source, but I don't have time right now to chase this. The hardware runs fine, other than refusing to reboot, which I put down to the usual BIOS ACPI table stupidity. For the time being I'm going to put a filter on the kprints, but I'm curious if this sounds familiar to anyone. Note this happens with both the 32- and 64-bit kernels. I don't have a quick way to attach sysinfo(1) to this message, but if somebody can use that I'll figure something out. --lyndon
