Events/0 high cpu usage

Question

Hello
From yesterday i'm experiencing strange problem. Process "events/0" uses approximately 66% of CPU. I didnt do any major system changes or upgrade.
It's anoying becouse writing text is really delayed and if i'm writing a bit faster i "loose" some chars or even whole words.
Can anybody tell me what could be the problem or what to investigate because i have'nt any idea.

I'm experiencing the same problem as the above poster (although the cpu being under load switches from cpu0 to cpu1 periodically).  This is on a Thinkpad x61, running Arch i686.  The system pauses roughly every 2 seconds for about a half-second, making typing a bit of an ordeal.  Standard browsing doesn't seem to be significantly affected because the mouse is still operational while this is going on.
Browsing my logfiles, dmesg, etc doesn't seem to be showing anything unusual.  The problem is still present after dropping out of X, killing numerous daemons, disabling some standard culprits (wireless card), and finally dropping to single-user mode, so I suspect there is some driver I can't track down at fault.  However, I'm at the limit of my bugtracking ability and the difficulty in typing text is making it quite difficult to progress further.
What strikes me as strange about this is that it has been several days since a major pacman - in particular, my pacman.log shows that my last updating was about 3 days ago, when I was fiddling around trying to fix a texlive issue, and this pausing definitely wasn't present then.
