Just upgraded to the latest amd64 snapshot,
and the high interrupts still appear.
It consistently appears after a suspend/resume;
top(1) starts showing something around 70% interrupt
on one processor, and 0 interrupt on the second processor.

Yes, this is the situation on my machine.
200 for clock, a few for ipi, negligible for others.

No. After the suspend/resume which somehow triggers the high interrupts,
systat still reports those values; maybe a few more for ipi, but the
total is still about 220.
Differing from my previous experience, the cpufreq (as governed by apmd -C)
stays at 800, the lowest possible value, and does not jump to 2000, the
highest possible value. Also, the machine gets generally slower, but
not unusably slow, as it did before.
Also, it does a second suspend (before, it never got to it).
And after the second resume, the high interrupts are gone!
A third suspend/resume triggers the high interrupts again.
A fourth suspend/resume "fixes" that again.
Is there something specific that I should test?
Would an acidump be useful for debugging this?
Thank you for your time
