JBD: Spotted dirty metadata buffer

[Norman Gaywood]

I'm getting these messages logged in /var/log/messages. Should I be worried?

The system has had a number of unclean shutdowns due to:

https://bugzilla.redhat.com/show_bug.cgi?id=550724

kernel versions that I've seen this on:

kernel-2.6.31.12-174.2.3.fc12.x86_64
kernel-2.6.32.6-36.fc12.x86_64

These are ext4 filesystems.
