> Can you try the hardware on another machine? Do other devices work? I have the same problem, but on completely different hardware. The problem is not caps lock itself, but turning off any keyboard LED. The LED is then off and the system does not respond. I can also reproduce it... ... by pressing num lock twice on the USB keyboard ... by pressing num (or caps) lock twice on a PS/2 keyboard (but when I unplug the USB keyboard this works fine) ... by pressing num lock once and starting X11 (because X11 turns of the LED) ... when I boot with init=/bin/sh Note that it crashes only with the standard UHCI driver, when I use the JE driver it does not crash. My software is more or less identical to Davids (also a Debian unstable system); I have only tried the 2.4.4 kernel.
