I have reported this bug upstream at
https://bugs.freedesktop.org/show_bug.cgi?id=24789.

kalessin, please subscribe to the upstream bug report by adding yourself
to the CC: field, so that you may provide the intel developers with any
additional information that they might need. I think they would be extra
happy if you could test an updated Karmic with xorg-edgers (bleeding
edge xorg-stuff, https://launchpad.net/~xorg-edgers/+archive/ppa) and
possibly also the latest mainline kernel at (currently v2.6.32-rc5/, you
only need to install the linux-image deb package for your platform), and
provide fresh logs and batchbuffer dumps.

You other guys, it is impossible to say if you have the same bug or not,
since there is a whole range of different underlying problems that may
lead to a GPU hang. Feel free to follow this bug report and the upstream
bug and test any proposed fixes. If your findings are different from
kalessin's you are experiencing a different freeze bug and you should
file a new bug report.

There are a few workarounds that you may try for the time being. One is
testing a newer mainline kernel as mentioned above (low chance of
working, but possible). Another is to disable kernel mode setting (KMS)
by adding the option nomodeset to the kernel command line ('Esc' at boot
to show the Grub boot menu, 'e' to edit the current choice, add
'nomodeset' after 'quiet' and 'splash'). In time there may also be
alternative driver versions in the x-retro [1] and x-updates [2] PPAs.
Currently, there isn't much there though.
