I keep getting the following kernel panic. Can anyone help me, please? As a test I have just change HDD to SSD and update memory from 2 GB to 8 GB. All said to be compatible with mac. Upgraded os x to Mountain Lion. Clean install from USB stick. Still the kernel panic happens a lot. What seems to be wrong?

You might want to check the check if you just changed it. There is probably a faulty one. – Matthieu Riegler May 22 '13 at 17:15
Check what? If its the ram and SSD they are completely new and OK. Same error happened over and over with old HDD and ram. Also that ran on Snow Leopard. – Simon May 22 '13 at 17:59

Apple Support has a page on Kernel Panics, including troubleshooting repeated KPs.

In my experience, they most often have to do with hardware changes / external mounting and unmounting, but of course YMMV.

Is it possible to read anything from the kernel panic above? – Simon May 23 '13 at 15:47
Not unless you are a real adept at reading logs. Easier to examine what actions you might have taken, in conjunction with using Apple's info as linked. – Zo219 May 25 '13 at 11:08

Its a probable RAM issue. Take out the RAM, clean them up, and put it again in the slots. It also happens when one of the RAM gets faulty, or is not properly attached.
