------- Comment #13 from [email protected]  2009-02-01 13:03 -------
Another rebuild, another set of results! This time I disabled CPUFREQ (I'm not
sure if my Celeron chip supports any of the schemes anyway), changing nothing
else, and the boot failure no longer happened (the slowness was still there
though).

It occurs, though, that the PS/2 issue may well be a red herring.  Thinking
about it: surely the reason powertop rated it as the highest cause of wakeups
was because I was holding-down a key throughout the data-collecting period!

I sought to try and discount this by entering a screen session, then issuing:

sleep 5; powertop -d > ptop.txt

then detaching from that screen and waiting, while leaving the keyboard alone. 
Result: 20 seconds later I reattached to the screen, but the operation was
still ongoing.  It didn't exit until I'd held down a key for a couple of
seconds (less than 5, so this seems to suggest that powertop had begun to
execute while I was detached, at least).

What do you make of the contrast between the instant output of commands like
ps, ls and cat, and the SLOOOW operation of those like top or powertop?
