I've got masses of these messages - about 100-200 per second filling my
logs. It seems that they came through as such a rate that the dmesg
buffer emptied of everything else before syslogd started.

I can try to get a full boot log later when I get home.

The interrupt counts don't actually seem to increase, I checked
/proc/interrupts several times in a row and there's no change to the
8042 interrupt counts:
