Description Dave Swegen 2001-11-14 15:50:00 UTC 
A while back we were evaluating using ext2 in conjunction with FreeBSD 4.1 for one of our products. However we came across a pretty bad problem, in that the kernel died (no panic messages as I recall). The cause seemed to be when a fifo was created on an ext2 fs.

How-To-Repeat: Haven't looked at it for a while, but AFAIK it should be enough to do a mkfifo on an ext2 partition. We discovered it when we were restoring a backup from tape.
