Good. I had seen this a month ago when I upgraded to FC13 (when it was
rawhide) and it disappeared once I upgraded to the real FC13. So I
blamed it on the alpha-rawhide X org driver. I could not reproduce this on
FC13 with an ES1000 in a SuperMicro (some X8DBN+).
So, can you send to me, please:
- lspci -vvvv
- cat /var/log/Xorg.0.log
- rpm -qa
- dmidecode
- dmesg
- xl dmesg
That way I should have enough data to see if I can track this errant
issue down.

Is this during shutdown or startup?
