Comment:
I've got similar issue with Optimus brand celeron based laptop with sis
graphic chip (which may imply it's sis-chipset based).

Kernel stopped booting, but after few seconds it detected soft-lockup and displayed stack backtrace. EIP was at mwait_idle(). 
So I've added 'idle=poll' to kernel command line. Similar hang, EIP at poll_idle().

I was able to boot after REMOVING 'noapic nolapic' from kernel command
line.
