Comment 61 for bug 348428

The change from 0u1 to 0u2 is the inclusion of these two patches cherrypicked from upstream, to solve bug #344740 which affects i855 chipsets:

114_fix_xv_with_non_gem.patch
115_fix_crash_xv_overlay.patch

Both are just tiny one-liners, but as Yoda says, "Size matters not!"

Anyway, I was a touch skeptical at the time that these patches could lead to regressions. Christoph's testing seems to confirm that is indeed the case here.

Of the two, 114 seems the most suspicious since it deals with the memory manager. 115 sounds like it corrects a crash situation, so if it is innocent here it would be nice to keep it.

I have uploaded a fix which disables 114. Please test and verify this resolves the user switching issue. If not, we can also try reverting 115.
