Hi all,

This morning I wanted to edit an ISO to instruct the kernel to redirect its
output to serial.

i.e 

# sudo vnconfig -v -c /dev/vn0 5.3-BETA1-i386-miniinst.iso
# sudo mount -t cd9660 -o rw /dev/vn0 /mnt
# sudo tcsh
# echo "/boot/loader -h" > boot.config
boot.config: Read-only file system.

Forget the afforementioned error. 

The problem that I have is now when I issue a df(1) my shell hangs: 

e.g.

# df -h
^C^C^D
^C^C^D

# ps -aux | grep df 
username 3333  0.0  0.0   212   96  p2  D+    9:04AM   0:00.00 df -h
username 3332  0.0  0.0   212   96  p1  D+    9:04AM   0:00.00 df -h

# kill -9 3333 3332

# ps -aux | grep df
username 3333  0.0  0.0   212   96  p2  D+    9:04AM   0:00.00 df -h
username 3332  0.0  0.0   212   96  p1  D+    9:04AM   0:00.00 df -h

No change.

I'm not sure what has hung here, nor am I sure how to 'un-hang' my shell.

Any thoughts anyone ?
