Description Tim Yamin 2009-01-01 14:08:25 UTC 
I had problems with DRI not working (PCI GART not mapping) on a system configured with 64KB pages. Lowering the page size to 16KB fixes the problem, but it would be nice to add an error message to the DRI code to indicate why the mapping failed and what the user should change.

Patch to be attached.

Cheers,

Tim
