I've been experiencing a really annoying problem with a FreeBSD setup on my laptop. The setup is as follows:

FreeBSD 9.1 / KDE4 desktop / Broadcom wireless 4313 through NDIS / Intel GPU with the new KMS driver.

The problem occurs some time after turning on the laptop, the desktop becomes sluggish. When checking the processes, upowerd is taking 100% cpu and cannot be killed. And either I reboot the system or it ends up rebooting on its own. And lately, such reboots are affecting the filesystem: I had to boot on live system and repair the damaged partitions.

Any pointers to what might cause this or how to prevent it ?

There is no upowerd on FreeBSD. – user34048 Mar 12 '13 at 13:23
@Simon Where is this upowerd then coming from? – Bernhard Mar 12 '13 at 13:50
