Kernel oops with ext3 and software raid



Am using RedHat 7.3 with software raid. it was crashing from time to time
so i desided to investigate. after running some stress tests on it it died
with a kernel message (see below). it might not be ext3 related but since
I was running redhat with ext2 for some time without problems (not on the
same machine) I thought it might have somthing to do with the fs.

Any ideas. I'll try converting to ext2 to see if it solves the problem.
