Comment 3 for bug 55689

It seems unrelated to ipw, switching to edgy didn't change things. But searching inside here, I got a possible solution in bug #67293, specific for my setup (hp6320). It came out it should be an hardware related issue, since a workaround is to remove a module manually before shutdown. I'm doing some tests on it, to have the exact picture. Since now thanks a lot for the support!
Ciao.
