For those who experience crashes on sleep and/or wakeup (typically due to USB) with 2.6.14, I made a test patch that might help. [ ... ]Ben, I just compiled and installed a 2.6.14.1 from kernel.org with none of your patches from this thread applied to it, and I have no sleep/wakeup probs with it so far: about 3 instances of sleep/wakeup until now, all of them successful. Maybe I even made it a bit more complicated for the system, as I connected a USB HUB, with 4 ports, to the machine: It just seems to work ...
Only newer machines with a NEC USB2 chip that shares interrupts appear to be affected by the problem. Ben.
