This person is actually encountering a bug though and I think we can
help them report that bug. It seems that your system is having a kernel
issue. This can be reported from your system using the command
'ubuntu-bug linux' in a terminal which will gather detailed information
about system and create a new bug report in the bug tracker for you.
Thanks and good luck!
