The 2.6.32-16 kernel *is* the kernel from the PPA; if that crashed, then it seems that you were just lucky while testing the PPA packages.
To debug further, it would be useful if you could do the following: - Install the latest drm-intel-next mainline kernel from [1] (instructions for how to do it on [2]). - Reboot the computer. If the boot menu shows, choose the 2.6.33-997 kernel. If not, you probably booted it anyway, you can check with `uname -a`. - Wait until X crashes - Copy GPU error info: `cp /sys/kernel/debug/dri/0/i915_error_state ~` - Check if ~/i915_error_state says something like "No error detected" or has lots of information, If no error, STOP. - Collect some corresponding logs: `dmesg >~/dmesg.txt`, `cp /var/log/Xorg.0.log.old ~` - Upload the files dmesg.txt, Xorg.0.log and i915_error_state from your home directory to here. This will hopefully catch more information about the error that is occurring, which we will be able to send upstream.
