I am not sure if that is related, but I can also panic it with just cp -a /usr/src to the WDC disk. butter# mount /dev/ad4s1a on / (ufs, local) devfs on /dev (devfs, local, multilabel) /dev/ad4s1e on /tmp (ufs, local, soft-updates) /dev/ad4s1f on /usr (ufs, local, soft-updates) /dev/ad4s1d on /var (ufs, local, soft-updates) butter# 2gigs of ram and 4 gigs of swap. butter# swapinfo Device 1K-blocks Used Avail Capacity /dev/ad4s1b 4157984 0 4157984 0% butter# I can also panic the machine with : newfs -O 2 /dev/ad8 mount /dev/ad8 /a mkdir /a/1 /a/2 cp -a /usr/src /a/1 & cp -a /usr/src /a/2 & And then wait 30 seconds to a minute. I get a bunch of g_vfs_done():ad8[write(offset=146023743488,length=16384)]error=6 errors on the console and then the machine locks up entirely, keyboard and keyboard lights unresponsive. I had looked for devclass_get_name and found: http://www.freebsd.org/cgi/query-pr.cgi?pr=85728&cat= but that is old and closed, from releng 6, 2007 timeframe.
