But, remember this is just -mm2, so any current BK fixes that change it wouldn't be in here, including the keyboard timer fixes that you were talking about. Andrew, I noticed that you picked up Ingo's timer fix in 2.5.41-mm2 as timer-tricks.patch. Despite this, Specweb ran for about 10 minutes on, then failed with the oops below. 2.5.41, without Ingo's patch oopses in seconds. It's very hard to get results out of Specweb when it is crashing this often. Could a misbehaving timer be causing the TCP errors too? I'd never seen them before 2.5.40. I don't know how closely the TCP errors occurred to the timer oops.
