Hi,
Try experimenting with kern.eventtimer.periodic and kern.eventtimer.idletick.
If this fixes it for you, please file a PR with all the relevant details.
Thanks!

Hi,

can you give/point to some info about this?
btw, I just noticed that on this hardware I get:
9.1-STABLE:
vmstat -i
interrupt total rate
irq3: uart1 931

What's the output of sysctl kern.eventtimer?
kern.eventtimer.periodic is 0
Does the bad behavior
change if you set kern.eventimer.periodic=1?

I still firmly believe the ACPI event timer code is racy, and what we
may be seeing here is the fallout from that.
It's very possible that we're missing interrupts here - the new
eventtimer code that made it into 9.x puts the halt behind a critical
section, with interrupts disabled. The only
