I know it doesn't trigger too often for most users, but still, for us,
once a week per server on 2 production servers we installed FreeBSD 5
and 6 on, is way too often. :-(

More so because these kernel panics on SMP systems tend to utterly
destroy soft-updates consistency giving fsck quite a workout and
resulting in data loss...

I'll retest that one, but it wasn't fixed yet in -CURRENT of a month ago.

I've tried all suggestions so far, but to no avail on most servers. Too
many broken ACPI implementations I fear... Too bad motherboard vendors
don't take the time to push proper software in their flash.

In any case, thanks for thinking along with me. :-)
