My computer is currently in the "nobody cared" state.

The keyboard issue happens every time I get the "nobody cared" message. Unfortunately, this regression requires me to wait a long time before it shows itself. As I mentioned in my original e-mail, the "nobody cared" message appears at 3:00 or 5:00 in the morning. However, I can write a cron job which saves the contents of /proc/interrupts every minute or so. If this would be helpful, please let me know. >> Note 2: Another interesting thing which might be relevant is the following >> message which appears in dmesg some time after I boot: >> >> --- 8< --- >> hda-intel: IRQ timing workaround is activated for card #0.
