Same here, I can confirm that.
At first I haven't noticed that it only happened while on battery power, and after some testing it indeed is true.
Also, the workaround suggested by David (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/651008/comments/4) does work as a charm.
I guess it is too late to get it fixed for maverick, but I hope the fix comes along soon. If there's anything I can help (testing, providing information), let me know.
