I have also seen the same error today.

I wonder if it is related?

Machine hanging after X/GDM filled / with log files. Machine doing nothing - left during the day running.

Got back from work, discovered my desktop PC was "frozen" - at least the graphics were dead (garbage on screen). Constant disk I/O. Logged in remotely via SSH - disk activity was kjournald ..turned out my disk was 100% full. Looking - it was all in /var/log and /var/log/gdm/ - 2x 1 GB log files :

/var/log/Xorg.0.log
/var/log/gdm/:0.log

X/GDM dead. I have saved these files and attach the top 500 lines of each.

Stand out :

I also attach the Xorg.0.log.old - it seems fine.

Looking at /var/log/syslog, I see an error at :

CRON (update-motd) runs for a bit, until it sticks at 16:10:02. Nothing in syslog after.

I attach the syslog as well.

I also attach lspci -vvvnn
