When KMS is available, UXA is the default acceleration used by the driver, (EXA is the default otherwise). +Known issue: + + Some Linux kernel versions (such as 2.6.29) are known to have + broken PAT code that causes recent versions of this driver to + fail, (which can manifest as the X server simply not + starting). This can be verified by adding the "nopat" option + to the kernel command-line and seeing the failure go away. We + hope that newer kernels in the 2.6.29.x as well as 2.6.30 and + above will have working PAT code. + Some of the most notable bugs fixed in 2.7.0 include: [GM45 965GM] bad htotal causes panel startup failure -- cgit v1.2.3
