Bug #1083: dfly-2.0.0-REL: panic: hammer: insufficient undo FIFO	space!

Author: M. K.
Status: Resolved
Priority: Normal
Target version: 

OS: dfly-2.0.0-REL

I backed up my 5GB win2k ntfs partition to a disk image file on my Hammer FS
(6GB in size). When removing the image file, panic occurs.

To reproduce panic:

NOTE: assuming Hammer FS is mounted on /hammer dir and /root is symlinked to

# cd /root
# cat /dev/ad0s1 > c.img
# rm c.img
