--- Comment #2 from Len Brown <l...@kernel.org> 2011-07-16 23:16:41 ---
please enable CONFIG_CPU_IDLE=y again.
boot with both command line params
intel_idle.max_cstate=0
processor.max_cstate=1
and capture the complete dmesg
increase N in processor.max_cstate=N
until failure or until you stop seeing a max_cstate
message in dmesg (probably at 4).
then increase N in intel_idle.max_cstate=N
from 1 onward until no max_cstate message.
capture the dmesg for the last one that works
and report the 1st one to fail.
