Steps to reproduce:

I was playing with raid failure simulation.
Created raid5 device on loop devices and failed 2 out of 3 devices on which raid
has been setup.
Comment 1 Adrian Bunk 2006-07-19 07:58:26 UTC 
Can you reproduce this problem with a vanilla 2.6.17 kernel from ftp.kernel.org?

If yes, please post the output with kernel 2.6.17.

If no, please close this bug and contact RedHat for support.
