I always used to get this when I ran console screen saver kernel modules
(like firesaver and the like). I noticed that when those were running,
the system spent almost all of its time servicing interrupts. If I had to
guess, in my particular case, it was so busy servicing whatever interrupts
were caused/generated by the running of the screen saver, that it was
missing the RTC (real time clock) interrupts.
Just a guess based on my experiences.

"Deep" is a word like "theory" or "semantic" -- it implies all sorts of
marvelous things. It's one thing to be able to say "I've got a
theory", quite another to say "I've got a semantic theory", but, ah,
those who can claim "I've got a deep semantic theory", they are truly
blessed.
