Hi, all. I just wanted to chime in that I am experiencing similar issues. The system will freeze quite often, typically after sitting unused for long periods of time and also during certain graphics-intensive operations (usually when using flash video player inside a browser). By 'freeze' I mean that I will be able to move the cursor and get responses from certain UI elements but not others, then all UI becomes unresponsive until I reboot.
I am running the H61N-USB3 with a custom F2-edited DSDT for HDMI audio. I actually have F3 BIOS now so I may switch that out for the DSDT uploaded by jaredkipe. I am also using the lynx2mac Realtek drivers.
One piece of advice for everyone in this thread - crank down your graphics memory as much as possible in the BIOS (32MB)! Apple hardware disregards this BIOS setting anyway because no equivalent exists on Apple motherboards. Instead, the OS reserves memory for the HD3000 based on system variables and driver settings regardless of the BIOS setting. Really all you are doing is wasting memory pages if you reserve it in BIOS! This was confirmed by RevoGirl.
I recommend everyone read through some of her entries on the HD3000 artifacts and instability: https://revogirl.wordpress.com/2012/01/ ... roperties/
I am hoping that 10.7.3 may bring some stability fixes to the system since it contains graphics driver updates but I am not putting much faith in it. I may try changing the network driver but I am fairly confident the problems are tied to the HD3000 after reading about so many users with the same issue.
Has anyone been able to successfully resolve this problem? I may try a larger amount of memory or a different manufacturer next and see if that affects the system freezes.
