The process modprobe got stuck in an "uninterruptible" state. Other 
processes that are in the same state are: canon, usbview, khubdand and 
vmware-vmx. I am guessing that they are all stuck because they are trying 
to use the USB ports.

I am not sure if this is enough information to make up a useful bug report. 
But it seems to be repeatable so I probably should file one anyway.

This may or may not be related (to the usb problem) but I am noticing that 
the memory footprint keeps growing on firefox-bin (144.9 Mb), xorg (140.5 
Mb) and nautilus (109.6 Mb). I have 1 Gb of memory (741 Mb is now used) and 
2 Gb of swap (513Mb is now used). Maybe this has something to do with my 
system getting slower over time.

My up-time is around 5 weeks. I was hoping that, over time, the problem 
would become more severe and thus more obvious. But it seems like it is 
just doing a slow and steady degrade over time.
