Comment 12 for bug 516909

Sounds like it's time to get busy backporting. Three different backporting options are currently being discussed on the ubuntu-x mailing list. I hope it is not left to users to fix this by installing a LBM (the third option being discussed), although the idea at https://lists.ubuntu.com/archives/ubuntu-x/2010-February/000751.html would make this much simpler.

BTW, the newly released Lucid package xserver-xorg-video-intel 2:2.9.1-1ubuntu6 will make it easier to debug this issue with kernel 2.6.32 - according to https://lists.ubuntu.com/archives/ubuntu-x/2010-February/000762.html it triggers the apport bug info collector when X freezes. Although on second thought, that is probably of limited use, since we now know that the issue is fixed with kernel 2.6.33.

There are also a few more Ironlake bug fixes in kernel 2.6.33-rc8 - see http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.33-rc8
