Hey Thomas,

Just started seeing this now during testing of Rafael's s/r fix:

[ 24.973955] clocksource: timekeeping watchdog on CPU3: Marking clocksource 'tsc' as unstable because the skew is too large:
[ 24.987744] clocksource: 'acpi_pm' wd_now: 2df835 wd_last: a6bb64 mask: ffffff
[ 24.999587] clocksource: 'tsc' cs_now: 2bbe793d1e cs_last: 296e28763c mask: ffffffffffffffff
[ 25.013400] clocksource: Switched to clocksource acpi_pm

In the previous boot it was CPU1.

And kernel is rc5+tip/master.

Any suggestions are always welcome.
