The first poulsbos used to crash badly when attempting to map the GTT write-combined, and IIRC it didn't even advertise write-combining capabilities on the PCI BAR. Has this been improved on lately or how is this handled currently?
It seems to be reliable in the current driver. Whether that is because I don't use the 3D engine and that causes problems I don't know. One thing longer term I want to poke at is cachability stuff to see if we can tune it a bit.
