I see. The lockup definately happens on both EHCI, UHCI and OHCI, but this issue may be a seperate one. > - The usb-storage device seems to have spontaneously > disconnected itself.

Given the spontaneous > disconnect, this is trouble. Indeed. I just tried inserting the very same external case on my notebook (running 2.6.8-rc1 UP), and it was fine. I plugged the usb connector in and out of my notebook as fast as I could, and it still wouldn't crash. Yet, on my server (dual AMD SMP) that would be a sure way to kill it. It seems like an SMP-only issue, at least to be. > - Some bogus diagnostics on non-error situations.

I'd be happy to help, if only I knew how :-) And btw, 2.6.10-rc1 seems a little better, although the lockups still come at some point (maybe not on first unplug, but then on second... race?) > - Dave > > p.s.
