I reported a socket stuck in "ESTABLISHED" the other day. I now believe
this to have been cause by the oopses generated when a network interface
is dropped and the module removed.
This is a nasty bug. Here are some oopses I generated by doing this while
upgrading the driver yesterday. By some miracle after this spurt of nasty
oopses, including one of the "Aieeee" variety, the machine is still alive,
and, er, fine :)
Cheers
Chris
