2.5.58: Kernel BUG at fs/devfs/base.c

Kernel: 2.5.58 + bitkeeper patches + a patch by Patrick Mochel to fix an initrd oops: http://www.uwsg.iu.edu/hypermail/linux/kernel/0301.1/2364.html

I hit the following BUG twice while working with GNU parted.
The first time I tried to remove (rm) a partition and create a smaller one in its place (mkpart). The second time I tried to remove a partition and create a larger one in its place. Both times the partitions were created with the proper size, but parted crashed with a segmentation fault.

Here's the important parts of the BUG:

parted: OOPS devfs.put: Poisoned put
