Hi, Sander, can you please have a try to following patch?
The reason for this issue is, in hpet_broadcast_enter(), it will return
directly if timer_deadline==0 without setting the channel, while
hpet_broadcast_exit() missed the checking.
As the timer_deadline is only changed in softirq context as per_cpu action, it
will not be changed between hpet_broadcast_entry()/hpet_broadcast_exit(), the
checking is safe.
We considered to use the num_present_cpu() instead of num_possible_cpu() in
hpet_broadcast_init(), but that seems not so important, since it is already
limited by HPET's channel number already.
