next in thread | raw e-mail | index | archive | help
We are running freeBSD current on a dual pentium 200. If we
mount fdesc with an /etc/fstab like so:
fdesc /dev fdesc rw,union
and then do something like:
bash$ cat /dev/stdout | somenonexistantfile
the machine reboots instantly.
this is the top of dmesg:
