Not even sysrq?

Same for me.

2.4.23 locks up hard. 2.4.22 worked perfectly (save the random usb
oops).

I was not able to capture a register trace or a process dump with
sysrq because this box has a usb keyboard and usb seems to get
shot. I've plugged a ps/2 keyboard to get more details the next
lock-up. If this fail, I might try the NMI oopser.
