------- Comment #47 from [EMAIL PROTECTED]  2008-01-05 03:31 -------
We use timer broadcasting in C2 anyway, but this does not change the problem at
all. We can not avoid a situation like this:

CPU goes idle
Timer interrupt happens while interrupts are disabled right before we go into
C2
We wake up only when some other interrupt (keyboard, network whatever) comes
in.

This is completely independent of local apic timer or hpet/pit broadcast mode.

To verify this we can simply backout the quirk (git commit
c1c306344669ca40255e36192b101060ffbb1271) and add "noapictimer" to the kernel
command line.
