Public bug reported:
System: Hardy 8.04.1, Toshiba Tecra A8 Notebook, intel 3945 WLAN
disabled per hardware switch.
Trying to figure out why, lately, Hardy grows slow and hardly responsive
after a day of working, I found my dmesg output filling up with messages
like this:

Not sure whether this is the reason for the system slowing down but at least it
doesn't look that good, does it?
