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

Hello Michel,

Allright, this time it worked :-)

I probably misunderstood that the "How to build mesa" page was only
dealing with the Gallium driver.

So, back to your initial question ;-)

> Does the classic driver still work?

Kinda. glxgears rendering isn't corrupted as with the Gallium driver,
but the system instantly locks up. This is a recurrent problem on
IA-64, so the (unknown) root cause
(http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg46848.html)
is probably still the same.

It's noteworthy however that, contrarily to the Gallium driver, both
glxinfo and glxgears generate unaligned accesses
(http://www.gelato.unsw.edu.au/IA64wiki/UnalignedAccesses) with the
classic driver.

Hope this helps,
