Description of problem:
The kernel switch from tsc to refined-jiffies during boot.
Jul 21 08:40:35 localhost kernel: Clocksource tsc unstable (delta = 133764044 ns)
Jul 21 08:40:35 localhost kernel: Switched to clocksource refined-jiffies
with refined-jiffies, system clock is really slow, 4-5 times slower than real time.
I can switch back to tsc with
echo tsc > /sys/devices/system/clocksource/clocksource0/current_clocksource
But tht system freeze ramdomly.
My hardware is a Baytrail based HP Pavilion x2 - 10-k020nf.
I have tested Ubuntu 14.10 and the problem does not occur.
Steps to Reproduce:
is 4.1.7 in testing working any better ?
tested with 4.1.8-1
Same problem. The clocksource siwtched to refined-jiffies and the clock is still slow.
kernel: timekeeping watchdog: Marking clocksource 'tsc' as unstable, because the skew is too large:
kernel: 'refined-jiffies' wd_now: fffbf891 wd_last: fffbf69c mask: ffffffff
kernel: 'tsc' cs_now: 1a9335e0f0 cs_last: 1a6675c050 mask: ffffffffff
kernel: Switched to clocksource refined-jiffies
Mass-reassigning all bugs with "kernel" in the Source RPM field that are assigned to tmb, to the kernel packagers group, because tmb is currently MIA.
What about newer kernels?

It's 2½ years later, still no reply.
Closing as OLD.
