Does booting with "nolapic" help on all of the affected systems?
Also, does disabling the CPUidle during boot help?
Finally, is the problem reproducible with CONFIG_NO_HZ unset?
Well on two machines, nolapic cures the boot hang and on one machine it
cures the random shutdown hangs.
I'll compile a kernel with CONFIG_NO_HZ to see what happens but how do I
disable cpuidle during boot? I've checked the kernel-parameters.txt but
there's no cpuidle related boot parameter there.
Booting with intel_idle.max_cstate=0 should do the trick.
Okay but on Asus X61S idle fallbacks to cpuidle:
intel_idle: MWAIT substates: 0x3122220
intel_idle: does not run on family 6 model 23
so forcing max_cstate to 0 will turn off the cpuidle on those machines too?
