Bug Description

Not sure on how to reproduce this one.
Am using a rather old HP Omnibook 6100, seems that when running on battery power the computer freezes for periods of time, perhaps 30 seconds, after which it continues normally and pauses again several seconds later. I don't even know where to begin with this one. At a wild guess it may be related to my bcm4309 pcmcia card which uses ndiswrapper to function,but I don't really have a clue.

Could you perhaps try taking out that pcmcia card and see if the problem persists?

Well I took it out, the first reboot the computer turned off half-way
through booting. Second time it made it to the desktop, but took an
extra minute to load, keeping the message that nautilus was being loaded.
After this the computer had the symptoms I described, e.g. clicking on
PLACES -> HOME takes about 1 minute to complete with no disc activity.

Just to put it in comparison, Dapper, Edgy, Debian Sarge and Knoppix are
all OK. Something strange with Feisty, perhaps the fact that it is
pre-release :)

It does still persist. Also if the laptop is running on mains power and
then that is disconnected then it runs well on battery power. Booting
using battery power is what causes problems. When running on mains I
have to say it runs quite well. Well enough, in fact, that I have been
able to do some Python development in Eclipse. Impressive!
