i've got the same issue; microsoft natural pro keyboard connected via
usb, system hard hangs when i turn caps lock off [i can turn it on once,
turning it off hangs it]. this is on a compaq prosignia desktop, and
repros on kernels 2.4.4-ac4, -ac8, and -ac13. other usb devices work
fine; i haven't tried this keyboard on a different machine.
let me know if you need more info.
