<pre>Please file cfl separately as TSC is not mean to be broken on new hardware, and
please let peterz/hpj know.
<4>[ 134.519360] clocksource: timekeeping watchdog on CPU4: Marking
clocksource 'tsc' as unstable because the skew is too large:
<4>[ 134.519436] clocksource: 'hpet' wd_now: c05a4d67
wd_last: bfc4584b mask: ffffffff
<4>[ 134.519450] clocksource: 'tsc' cs_now: 72c02e8d6e
cs_last: 7261d1ce0f mask: ffffffffffffffff
<6>[ 134.520117] tsc: Marking TSC unstable due to clocksource watchdog
<4>[ 134.520482] TSC found unstable after boot, most likely due to broken
