After upgrading to Lion a few days ago, my iMac has had around 5 kernel panics. Kernel panics were never a problem with 10.6. They mainly happen when watching YouTube videos (maybe a flash issue?) All help is greatly appreciated!
Same issue here, sort of. Not watching videos. But it does seem to only occur when using Safari. I get little green pixels all over the screen and the only two ways to fix it is to restart, or shut the screen off and then back on. Both of those fix it immediately. Never had it happen on 10.6 and it happens way too often on Lion.
