Yesterday my Mac crashed and after trying to turn it on again I recieved a message like this:

And I know there is a similar post and a good answer to that.
I can't access Recovery HD. When I try to do it by hitting Cmd–R or Alt while booting, Mac freezes and does nothing except generating a lot of heat around CPU. I can only turn it on, do nothing and wait for the kernel message above.
What can I do?

I'd advise you to boot your Mac from the system DVD and check the internal disk. The coincidence of
kext scan
failing and therecovery HD
unreachable let me diagnose a major disk (and not just filesystem) trouble. The CPU overheating might be a consequence of a fool'sfsck
.If you don't have a system DVD to boot your Mac (which is the case since Lion), I advise you to ask a colleague who have the exact same MacOS X version to build you one.
