Certain lockups with random oops occur all through kernel 2.6.16.19. Some of lockups are SMP only oopses (sorry but I didn't catch them exactly to a file), other are usually like this attached file As a general rule, if both 1) SMP 2) EHCI (usb 2.0) Are enabled and USB2.0 devices are used frequently, then kernel lockup appear between few minutes and 1 day. It is very annoying Disabling either SMP or the EHCI fixes the lockups. Probably some missing spin_lock or whatever in EHCI... Emard
