[BUG] x2APIC lockup on Dell machines

Open khale opened this issue 5 years ago • 2 comments

We have a Dell R430 that we're doing some testing on, and when we ran into an issue where we receive a spurious interrupt and the machine locks up in the bootup sequence (just about when interrupts are enabled in init.c).

Curious thing is that when we disable x2APIC mode in the BIOS the issue goes away. Is there possibly some x2APIC/SPIV interaction we're missing here?
