Lid actions typically trigger SMI code, so it's entirely capable of
destroying CPU state in such a way that the kernel falls over (and
probably even in ways that cause the kernel to turn green, emit pleasing
warbling noises or invade neighbouring pieces of hardware). In this case
it seems to be SMP specific - the system's entirely stable in UP mode.
It's greatly vexing.
