My computer is currently in the "nobody cared" state. Here are the current
contents of /proc/interrupts:

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.

It seems to use IRQ 22. I thought that there might be a connection, but it looks
like it isn't relevant.

Thank you; I appreciate your help.
