Have been running Karmic alpha 2 for approx 5 hours now.

Good news is that the MTRR errors are gone.
Bad news is the freezes are still happening.

Two lockups. One occurred when I had firefox open, lots of tabs open,
'Normal' visual effects enabled. REISUB'ed.

Decided to try turning off visual effects, but got another lockup, this
time in terminal looking through kernel logs from the last lockup
looking for clues :)

I did notice that for approx a minute before the lockup, everything in
the terminal went real slow. Like, scrolling via mouse wheel would take
2 seconds before it would start scrolling. Very laggy. It's quite
probable that this has happened with past freezes without me noticing
however, as I've found some websites slow my computer down to a crawl
anyway (probably due to flash).

Nothing in the logs showing anything. For what it's worth, I also got
the lockup on the livecd too and I noticed before it happened I had a
slight font corruption (every instance of 'e' had a line through it).
Funnily enough, I also noticed this in terminal before it locked up
(this time 'r' was missing a bit) so I don't know if it's related or not.

I've reverted to intel 2.4 drivers (
https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4 )
and they've been stable as a rock, full compositing (albeit slowish,
it's only intel 815 :)

Let me know if there's any diagnostic tools I can run to give some more
information. Maybe a version of the intel drivers with verbose debugging
output or something. I don't mind it running a little slow while I'm
testing, I just want this bug sorted. :)
