Two tears ago, I buildt a HackPro using X58A-UD3R and ATI Radeon HD 5700, I7 2,8 Ghz, memory 6 Gb 1600 Mhz
I use mainly Snow leopard 10.6.8 and all works fine.
On different partitions I installed Lion and mountain Lion
I upgraded recently Lion to 10.7.5 and Mountain Lion to 10.8.2.
Now I have random KP 1 time over 3 to 5 at boot, only with Lion or mountain Lion.
2 kexts are pointed
ATI support
ATI5000Controller
I did some search but I didn't find solution to that.
I tryed to put video kexts from SL replacing Lions'one, but this gave grey display.
So... if someone has an ATI 5700 running fine under LION or Mountain lion
please exchange.
Thanks
Leon
