Subject: [BUG] 3.3.0-rcX: kjournald

I'm not sure if I caught a complete instance of this in "syslog", but
here's what I've been seeing with 3.3.0-rc[1-3] kernels.  Shortly after
booting multi-user, logging in, and attempting a package build, the
"fun" starts: the following message scrolls repeatedly (possibly with
different details) across the console.  To date, I've had to hit the
reset switch to recover, which is why I'm not sure whether I caught a
complete syslog entry.
