Bug#622299: Corrupt GL rendering with KMS (r300) enabled on IA-64 platform (Itanium)



Package: libgl1-mesa-dri
Version: 7.10-4
Severity: grave

GL rendering is completely garbaged (see attached screenshot of
glxgears) and thus unusable when KMS is enabled with libgl1-mesa-dri
7.10-4 in today's Debian "Wheezy" Testing updates. Disabling KMS fixes
the problem.

Previous libgl1-mesa-dri 7.7.1-4 doesn't have this issue. Simply
reverting libgl1-mesa-dri to 7.7.1-4 (while keeping every other
packages up-to-date) by invoking dpkg -i --force-downgrade
libgl1-mesa-dri_7.7.1-4_ia64.deb fixes this issue. So, this definitely
sounds like a regression introduced with current libgl1-mesa-dri
7.10-4.
