>Description:
System will panic when under heavy I/O load. Thus far,
panics have been induced by reading from a scsi tape drive,
and NFS over a tlp0 interface. The wi0 interface does not
appear to have to be busy for the panic to occur.

>How-To-Repeat:
System will panic after ~40 seconds while running a:
$ dd if=/dev/nrst1 of=/dev/null bs=64k

>Fix:
# ifconfig wi0 down
dd runs fine, system is stable.
