A quick and dirty circumvention might be to put the following in
rc.shutdown until the root cause of the panics can be found and
fixed. I use something similar to this to unmount NFS filesystems
to avoid a panic during 2.2 shutdown.
# Quick and dirty fix for dirty buffer panic during shutdown
for I in `df -tmfs | awk 'NR > 1 {print $6}'`; do
for J in `fstat -f $I | awk 'NR > 1 {print $3}'`; do
kill $J
done
done
sleep 20
for I in `df -tmfs | awk 'NR > 1 {print $6}'`; do
for J in `fstat -f $I | awk 'NR > 1 {print $3}'`; do
kill -9 $J
done
done
sleep 10
umount -vatmfs || echo MFS umount failed.
