Bug Description

I'm running 12.04 and I was creating a USB boot disk from 11.10 ISO on my filesystem. Once it was ready I ejected the flash by draging and dropping the icon in unity launcher to Trash. I've seen a "device successfully ejected" message and then the following:

Unfortunately the computer froze couple of seconds afterwards (I don't think it is related to this bug as I'm experiencing that behavior couple of times a day) so I wasn't able to finish the bug reporting process.
I started this one using:
mmrazik@fry:~$ ubuntu-bug linux-image-3.2.0-17-generic-pae
and extracting the trace from syslog.
