Freeze when back from Sleep after 10.8.3 upgrade #iATKOS #ML2

Hi,



I have a Mac-Pro 1,1 2006, on which I was using 10.8.2 without any problem, except freeze issue when Bluetooth enable. After disabling it all was working like a charm. Graphic card ATI Radeon HD 5770 1024 Mo "PC Version flashed"



Now I upgrade to 10.8.3 and had 2 issues:



- Not able to make the Mac running from sleep to wake-up "black screen"

- Fixed by disabling all application at Start



- Now I can wake-up after a sleep, but after few minutes I got a freeze screen and have to reboot the Mac



any help will be very appreciated, otherwise will downgrade to 10.8.2



Thanks
