| |
one socket system with running cpu/memory stress test, got:
-- [45477.565642] timekeeping watchdog: Marking clocksource 'tsc' as unstable, because the skew is too large: [45477.565643] 'acpi_pm' wd_now: 32e642 wd_last: 71c8c5 mask: ffffff [45477.565644] 'tsc' cs_now: 4b80842681e0 cs_last: 4a48ac7d5a0a mask: ffffffffffffffff [45477.623779] Switched to clocksource acpi_pm
so acpi_pm reading between two timer are wrapped.
When that happen, should just disable clocksource_watchdog instead?
Thanks
Yinghai
