My software is OS X Lion 10.7.4 and I've reinstalled it 4 or 5 times to try to solve the kernel panic problems. It's better now, but still unstable. It's a Core i7 2.8 GHz (dual core) with 8 GB RAM and a Toshiba 750 GB hard drive.

This last was just 20 minutes ago. After the reboot, everything works well.

This has begun to happen after the latest OS update was installed. I've run memtest, checked the disk, and repaired permissions. The hard drive appears to be fine. Can anybody help me with this problem?

another panic 2 minutes ago..BSD process name corresponding to current thread: repair_packages –  Adriano Palmisano Jun 15 '12 at 23:37
    
Running repair permissions won't help in this sort of case, especially if you've not installed any software since you last ran it. –  CajunLuke Jun 15 '12 at 23:40

Repetitive kernel panics even after reinstalls (which rule out a software problem)... this points a lot towards a hardware problem. –  Renan Jun 15 '12 at 23:42

Can you take the machine into your local Apple Store or Apple Authorized reseller? Kernel panics that continue over OS reinstalls are indicative of hardware problems, possibly the logic board.

logic board????whats that?i went to the genius bar one month ago they did the hardware check and it seemed all right –  Adriano Palmisano Jun 15 '12 at 23:44
    
It's the mainboard where the CPU and GPU sit and the RAM plugs into. –  CajunLuke Jun 16 '12 at 0:23
    
it could be also.. –  Adriano Palmisano Jun 16 '12 at 0:37

Pay attention to the debug output. You're getting general protection faults (in the kernel panic message) and segmentation faults (in the configd crash message)--these are signs of memory trouble. Try running a memory test such as Memtest86+.

Edit: You stated that the system is running on third-party memory modules. You still have the OEM modules; installing laptop memory is a fairly simple job. Try looking at this page for information on how to do it.

brillant im checkin it..just time to do it –  Adriano Palmisano Jun 15 '12 at 23:56
    
it doesn't appears as a compatible mac software –  Adriano Palmisano Jun 16 '12 at 0:01
    
Try using the memory test on the Mac Hardware Test CD or DVD. –  DragonLord Jun 16 '12 at 0:03
    
i know but apple doesn't put the cd in the new boxes with lion..also to reinstall the os i made it with the internet connection from the apple store –  Adriano Palmisano Jun 16 '12 at 0:06
    
It should be on the install DVD. If you don't have it, I guess you'll have to try bringing it to the Genius Bar once again... –  DragonLord Jun 16 '12 at 0:13

If your computer is panicking when AppleHWSensor is loaded, if it's not a software problem, it's because your logic board is overheating. In that case this is expected behavior.
