SubjectRe: 2.6.8.1-ck7, Two Badnessess, one dump.
I upgraded from 2.6.8.1-ck5.

First off - this has been a landmark improvement for me. Running an
"emerge -a world" on my system has gone from a matter of minutes to a
matter of seconds.

The performance has been !outstanding!.

The first night of running I got this:

I shutdown, did an xfs_repair, and the error has not returned.

Two days later I got this:
