HI guys,

I really need help with my stupid laptop... I'm starting to feel the need of throwing it out the window.

I have a Mid 2010 MBP and ever since I upgraded to Lion, it's been incredibly unstable. Kernel Panic is the norm. I get it all the time during shut downs and sometimes during start up.

Now my problem is I'm trying to go into Recovery HD through Options at start, however, every time I try, Kernel Panic happens. This is my log:

Can anyone tell me what is going on? I already tried to verify and repair my disk in normal log in mode and I don't know what else I can do.

Thanks guys

The disk images framework should be able to mount the disk image outside of the kernel. In-kernel mounting is not the default since Mac OS X 10.5, IIRC, because it can cause security issues. You write, you have constant kernel panics. That means either your RAM is faulty or your HDD is faulty. Mac OS X HFS+, the file system on your Mac OS X startup disk(s) does not use data integrity checks, so that the responsible file system driver, including the kernel itself, can read corrupted data from a disk, even if he should not do this.

I would try a clean installation of Lion (backup, then erase the original installation first). If that does not help, check the above mentioned hardware with the appropriate tools.
 
This is now what happened when I tried to turn off my computer:
