    Encountering frequent kernel panics on my 13" 2011 MBP (i5/8gb/320gb). I recently upgraded to Mountain Lion and 8GB RAM. Can anyone shed light onto what the cause is based on these logs? I want to make sure its one or the other. It happens when I'm browsing the internet, both with Chrome and Firefox. Chrome has also been frequently crashing. The computer was completely stable before these upgrades and its driving me nuts.

    The only stuff I can make out are graphics and "windowserver," whatever that is. I know that is a system process so I recommend backing up your computer, restoring factory settings, reinstalling mountain lion, and restoring data

    I'd check the new RAM first. You may have either bad sticks, or they may not be seated properly...Try taking them out and trying them sequentially, if the problem goes away, you will need to get those new sticks replaced.

    Forgot to mention that if that doesn't work, if your computer came with CDs, try booting both of them by holding the d key when you press the power button. If there were no CDs, then boot holding the d key and run a hardware test. Finally if those don't work, set up a genius bar appointment and request them to do a hardware test


    Wow, if you were right, then I was WAAAAYYYYY off. I didn't even read the part that the OP replaced the memory

    Stop using Chrome. What year is your Mac? There is a well documented memory leak with Chrome that causes kernel panics in all the 2012 Macs equipped with the HD4000 (someone happened to mention graphics above me).

    I can't speak for Firefox, but Chrome ~21 def crashed my MBPr. I'm on Chrome Canary now (ver. ~23 last I checked) and it has been a far smoother experience. No panics since I switched to Chrome Canary.

    Edit: disregard that. I don't know how I missed that you have a 2011. The problem I mentioned is specifically with HD4000-equipped models.

    I don't think Chrome is the problem, as the RAM failed part of Memtest. Shame I don't have backup sticks so I can't reasonably do an RMA on a computer regularly used for work.

    It turned out to be the RAM. Don't buy Komputerbay. Kingston sticks fixed the problem.
