Bug description:
I have a Toshiba laptop (Satellite A65) with a built-in Ethernet
adapter, running Ubuntu Oneiric with the stock kernel 3.0.0-16.28.
After some time in operation, while the system is in use, the network
connection stops working and I find the following in /var/log/syslog:

Unloading/reloading the 8139too/8139cp modules doesn't help at that point,
only rebooting. Seeing as the logged stack trace goes through some SMP-related
functions, I am currently running this system with the "nosmp" kernel parameter
and so far that appears to be keeping this bug at bay.
