[nycbug-talk] High amount of interrupt activity when using FreeBSD CAM

[H. G.]

Greets folks.

Please tolerate today's stupid question:
Is a high amount of interrupts "normal" when using FreeBSD's ATAPICAM?
Perhaps there was a kernel tunable I forgot to tweak, or a kernel option I
forgot to compile in?

When using growisofs in FreeBSD through the CAM framework, top reports
almost 95% CPU time spent on just interrupts.
As you can imagine, the machine gets pretty lazy to stimuli when this
happens.

Pointers?  Comments?  Derisive laughter?

Thanks,
HG
