Description of problem:
Intermittent oopsen caused in the ext3/journaling code.
This went away when I switched to ext2.

Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
There is no statndard way to reproduce this. Typically, I would
have the machine running for a few hours/days, and then the oops
would happen. The machine would still be usable in both release and
debug kernels, sometimes after multiple oopsen.
	

Actual Results:  Here is the oops that typically happens:
