>Description:
See How-To-Repeat to get the precise thing I've done time and time again
to get this happening. The problem does not happen when the image is on an
ffs partition, so I suspect it's having some problems msdos-to-msdos or
such. All subsequent writes to ffs partitions will stall, yet writes to
the same msdos partition will go through.
All processes that hang have the STATE (from 'top') set to wdrain
They never come out of that state
>How-To-Repeat:
su
cd /mnt/msdos
dd if=/dev/zero bs=1024 count=760000 of=7
mdconfig -a -t vnode -u 7 -f 7
disklabel -r -w md7 auto
newfs /dev/md7c
mount /dev/md7c /mnt/7
chown me:mygroup /mnt/7
logout
cd /mnt/msdos/dump_to_cd_dir
mv * /mnt/7
>Fix:
Computer cannot be shut down and power has to be taken manually
