Sir, you are very correct:
/kernel: sc0: enabling tty intr. (set_keyboard)
/kernel: sc0: about to send command and data (set_keyboard)
/kernel: sc0: kbdc is LOCKED!! (scintr)
/kernel: sc0: kbdc is LOCKED!! (scintr)
/kernel: sc0: command:f3 data:0 ret:fa (set_keybard)
/kernel: sc0: kbdc is LOCKED!! (scintr)
and, most importantly: your patch appears to have worked - I'm happily
running X again w/o difficulty for the past few minutes, it looks fine.
Please remind me to buy you dinner should you be traveling to San
Francisco ;)
Thanks again and best regards,
Ian
