Problem Description:
I have seen the following oops while unmounting the root filesytem on system
shutdown. Previously, I had ran "prelink -av" and "sync". The root filesystem is
ext2 mounted with "noatime".

This is all I've been able to gather from the screen of my laptop:

Does this problem still happen with more recent kernels?
Comment 3 Felipe Alfaro Solana 2005-07-05 10:44:42 UTC
I haven't seen it anymore, so I'm closing this bug.
Thanks.
