I have an Asus EAH5770 (0x68b8) in my mac pro 1.1 with Mavericks using patched efi.boot
I have flashed the card and now is correctly recognized by the system (with only one display via VGA it works also boot screen) but sometimes, mostly after a wake from sleep i have graphics hang.
I have tried to patch the AMD5000Controller.kext adding the Vervet personality in Info.plist of the kext:
So the framebuffer seems to work properly:
Can you tell me please if I can fix sporadic graphics hangs?
Thanks in advance.
