Hey, folks. At the blocker review meeting today we agreed that we were not in a position to decide on the status of these potential blockers:

https://bugzilla.redhat.com/show_bug.cgi?id=677842 https://bugzilla.redhat.com/show_bug.cgi?id=677371

they apparently cause an unusable system as Shell repeatedly crashes and fallback mode does not kick in. We are unsure of the extent of the impact; several different reporters seem to have hit these (including the Chinese install testers, though they didn't add a comment to the bug, they mentioned it in their test report).

Looks like all post r600 ATI cards would be affected, something must have changed in mutter to trigger this, the quickest solution I can see at the moment is to rebase mesa and pray. If you want a targeted fix it'll take longer to actually work out why its going so horribly wrong.

Thanks for the info! Can you quantify 'longer'? If we delayed Alpha by a week, would that be enough time?
