Unfortunately, I think this was never resolved. On upgrading karmic to
lucid, the problem re-emerged, even though I was using the Option DRI
false workaround.
I've been suffering lockups/crashes at about the same frequency, every
2-3 hours say, for several months (except when I use Windows,

I'll be optimistic and hope lack of recent response means the issue is
gone away. :-)
In any case, the next step is to have you re-test this on lucid. If it
is not reproducible there we'll consider the problem resolved now.

I've also just reproduced this problem (Firefox scrolling) on fresh
Jaunty 9.04 live CD, using a 3COM wireless card rather than ndisgtk. I
think this means we can rule out anything to do with persistent
configuration errors or corrupted packages, or realplayer or ndiswrapper

Binary package hint: xserver-xorg-video-ati
This was a Ubuntu 8.04 fresh install on Viglen Dossier LX. Every few
hours, apparently randomly, everything freezes apart from the mouse
pointer. Ctrl-Alt-F1 or Ctrl-Alt-Del does nothing, but I can ping the
laptop.
Given that in bug 421842 you mentioned there had been a rough upgrade
with possibly corrupted packages, please first follow the directions to
repro this bug on a livecd updated to ~a-5; if you did have a faulty
upgrade I could imagine that it could cause both of these bugs, so we
should rule that
Thanks for that, but it looks like whatever improvements have been made
in the PPA, they don't affect this bug (or the new bug 421842).
I hadn't actually reinstalled the OS or run a live CD since reporting
this, just upgraded using Update Manager. The Karmic live CD (alpha-4)
seems to cause none

A new version of the -ati driver is now available in Karmic.
This is a significant update to -ati which brings in kernel mode-setting
(currently disabled) and scores of fixes for DRI2, EXA, etc.

If intrepid was somewhat better, jaunty has been considerably worse,
often freezing up within an hour using Firefox (I think it's
particularly common scrolling immediately after switching into the
Firefox window). I did have visual effects working for a while, and

Backtrace for Intrepid attached - it looks like essentially the same
problem in the same function (RADEONCPGetBuffer). It may be slightly
less frequent now, twice in three days. Might as well upgrade to Jaunty
now...
** Attachment added: backtrace during lockup on intrepid
Couldn't install upgrades with build-dep or aptitude, so upgraded to
8.10 Intrepid, xserver-xorg-core 2:1.5.2-2ubuntu3.1 , xserver-xorg-
video-ati 1:6.9.0+git20081003.f9826a56-0ubuntu2.1. Very similar effect
has occurred once, (although cursor movement was slow/jerky after lockup
this time).

Does this happen with a release later than hardy, have you ever tried?
