Hello Chris and Andrew, I did further testing and noticed that this patch fixes the boot errors and warnings and I get the XWindows. But XWindows freezes after some time. Thanks, -- Jaswinder Singh. On Wed, May 12, 2010 at 12:52 AM, Jaswinder Singh Rajput wrote: > Hello Chris and Andrew, > >

Directly read the GTT mapping for the contents of the batch buffers rather than relying on possibly stale CPU caches. Also for completeness scan the flushing/inactive lists for the current buffers - we are collecting error state after all. Signed-off-by: Chris Wilson ---
