--- Comment #7 from Chris Wilson <chris at chris-wilson.co.uk> ---
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
BIOS. Use 'tsc=unstable'.
