I installed OpenBSD 4.0 stable on an HP dx7300T.

Initially, I found the keyboard would not operate, but I fixed that by
running "disable uhci" at the boot prompt.

Now, I'm just finding that it seems to crash whenever I "overuse" a
console key. When I say "crash" there is no panic or anything I can
give you, the machine just locks solid.

For example, if I open vim and scroll to the bottom of the page, and
keep holding "down", or make a typo at the shell and press "backspace"
until I've erased all the way to the start, then pressed it a few more
times.
Basically anything you'd suggest should trigger the PC speaker. I have
disabled that speaker (in the BIOS) however, and found no change in
behaviour.

Any assistance appreciated.
