I see...

But after several times trials, I get below dmesg messages.
It is clear to see address of "timer->function" is 0xffffffff810d7010.
In calling stack, " [<ffffffff810d7010>] ?
clocksource_watchdog_kthread+0x40/0x40 ". So I guess timer->function is
clocksource_watchdog_kthread.

Hmm.. not exactly this function as this isn't timer->function for any timer.
But I think I have found the right function with this hint:
clocksource_watchdog()

Can you please try to test the attached patch, which must fix it.

Your patch fixes it!

Untested. I will
then post it with your Tested-by :)

Thank you
