Oops

[R Kimber]

I don't know enough about it to know whether this is a known problem (I
couldn't make much sense of what I found on Google), but it seems to be
a journal-related issue.  Is it likely that data has been corrupted?
Do I need to take any action?

2.6.12-9-amd64-k8-smp, Ubuntu 5.10, dual opteron 2GB
