I suggest trying kernel parameters:
intel_idle.max_cstate=0
maxcpus=1
and then:
nohpet
And see if these help.

OK, So I *guess* the problem is that when in deep C states the machine
may miss HPET timer interrupts and hence on wakeup it may be falling
into this state. Clearly this has regressed in Oneiric for some reason,
so we could work on bisecting this to find out when the regression
occurred.

>From the HPET kernel documentation:
The High Precision Event Timer (HPET) hardware is the future replacement

Each HPET can have up to 32 timers. It is possible to configure the
first two timers as legacy replacements for 8254 a
It looks like the IPI to wakeup the CPU at boot is not getting through.
Just to sanity check things, can you also test with just the kernel
parameter: "noapic" and see what happens. The output from
/proc/interrupts on the working 3.6 and not working 3.5 kernel would be
useful too.

Do you mind trying one more kernel parameter: noioapicreroute
..and let us know what happens. Thanks
