Correction. I _have_ been able to reproduce the problem with 2.2.5-22. It is not as predictable as 2.2.10, however.
Digging further, I have compiled a stock 2.2.4, without SCSI support at all. I couldn't reproduce the problem immediately, but will do further testing.

a) No replies to ping b) right-alt scrolllock does nothing anymore. It works great before the lockup, however.
The kernel debug patch you mean is the one by Scott Lurndal that can be found at http://reality.sgi.com/slurn_engr/, right? The latest patch there was for kernel 2.2.4, but as I could not reproduce the problem reliably with that kernel, I've updated the diff file to work on a stock 2.2.10. It is attached, maybe it can be useful to someone else. It works for me.
What exactly do you want me to do with the kernel debugger?
Ward.
