Mac OS X Leopard Kernel Panics getting absurd

Well, there could be quite a few things...

But, here's the top few that might help.

1) Download the Mac OS 10.5.8 Combo-Updater, and run that... 2) Check Virtual Box, and make sure that you have the latest version installed, along with the virtual box tools in your windows session / boot camp.

Let us know what happens.... And try checking your memory as suggested with the other answers...

Try reseting your RAM, and Hard drive. Disconnect all USB & Firewire devices, and if possible try running Tech Tool Pro, in extended hardware tests...

Something is obviously causing a problem... But there doesn't seem to be a obvious reason for it.

What antivirus packages do you have loaded? And do you have Virtual PC installed? Is there any software packages that you have installed or updated recently?

Kernel Panics are nearly always a sign of a hardware issue, most likely one of your memory sticks has developed errors. You can try finding out for sure by either running the Extended Test on the Apple Hardware Test section of your Restore DVD (hold D when you start up and have this disc inserted).

Alternatively you can try using memtest to test your RAM to isolate what stick has gone bad. It's also quite plausible the logic board is having issues instead but your best bet if you can't find out yourself (with the two tests I mentioned) is to take it to your local Apple Authorized Service Provider and have them check it out.

I've seen similar situations (same pmap_flush_tlbs error) with an '07 MacBook Pro (ATI X1600 graphics) from one of our deployed MBPs, and after about 3 or 4 days of wrestling with re-installations, diagnostics, etc, I decided to call Apple and get it replaced.

According to Apple tech, it could be a logic board problem. What you could do is try running diagnostics (hold down 'D' when booting up). However, I strongly recommend you to send it in to Apple - they'll get it replaced pronto.
