i am having this issue too, i don't know if it is the so called 'fermi freeze', but my hackintosh freezes every couple of minutes/hours... in the kernel log i see the following message: NVDA(OpenGL): Channel exception! exception type = 0x26 = FECS Err: Watchdog Timeout
i have lion 10.7.2 and GF GTX 560 ... i've also been reading on other forums, that this problem is flash related, so i installed adblock and flash blocker into my chrome browser ... since then i only become freeze after watching some flash videos, sometimes it happens with 2 videos, sometimes with 20, it is irregular... i haven't tried the looping video fix yet, the ad blocker is enough for now, i haven't had a freeze for 2 days now, even not after waking my computer from sleep
i would be really glad if someone came with a better solution
