Hi, Here's a trace with powerd/sleep states disabled, but I haven't set machdep.idle=spin. I'll try it with that in a sec. http://people.freebsd.org/~adrian/ath/ktr-notaskq-1.out.gz The entries are still out of whack in places, but it doesn't look like it's necessarily due to out of sync TSCs.. Adrian
