Kernel Panics non-stop

I was getting kernel panics 90%+ of the time a few seconds after starting the VM, the suggestion above fixed the issue. Nice find.
 
I think I spoke too soon about the boot flags mentioned in the link, but I have found that my KP's occur right after starting the VM, when the VM window with its fancy graphical effect while the VM is starting changes to the VM's BIOS screen. If I have the VM window resized to a large size (as it ends up after shutting down a VM) it will crash, but if I resize it to the smallest size it can be, it won't.

So guys try resizing your VM window to the minimum before starting it and post back whether it works for you.

Looks like you guys at Parallels may have a bug to fix :-)
 
Kernal Panic #70

I'm not sure if Parallels is causing this, but I've had up to 4 KP's daily not even using/opening Parallels. So far, this has added up to 70 KP's since July. However Parallels does show up at the top of the list each time in the crash reports, so something is always running in the background even when Parallels is not engaged/running.

The first notice I read involving Parallels causing KP's in Lion was supposedly because of a second party virus scanner that was given out by Parallels as an optional install. However, I didn't and haven't install it.

The other "ify" .kext file extensions that are showing up are a few from AudioHyjack (e.g. sound flower) and Little Snitch. I've removed them and still am getting the panics.

I did add the bootjack text posted here... we'll see if this is the fix. But what an immense pain... so much work lost. good thing I kept Snow Leopard on my MacbookPro!!! Running 10.7.2 and the latest Parallels 7 on an iMac 24" 2.8Ghz w/4 GB RAM.
 
@mikesreach
You can try uninstalling Parallels (it won't delete your VMs or settings unless you deliberately tell it to), reboot and see if you still get Kernel Panics.

Whatever the outcome, run a permissions repair before installing PDM7 again (in case what's causing this was an upgrade that wasn't able to update all files because of bad permissions).

uninstaller?

I think when giving advice that requires software, a link to that software would be extremely helpful. How and where would I find an "uninstaller" for Parallels?
 
Maybe you haven't noticed the links in my signature.
And, you maybe haven't also noticed that the .dmg or cd that you used to install PDM has an uninstaller package too.

External Monitor?

keithos27/mikesreach/ others - are you running an external monitor? P6 runs fine on my MBA until I connect an external monitor. Then I get a kp within minutes.

Funny that you ask.

I'm trying to find the cause of the KP's on my mother's MacPro. So far i did the "Extended Apple Hardware Test" and the "memtest on single-user-mode" (memtest all) and both passed successfully.

To note:
She bought her MacPro abroad and used it abroad without any problems. She got herself a RAM upgrade abroad, went from 4GB to 8GB and still used it abroad for a few more days without any KP's or problems.

She then flew home and followed my instructions, connected it to an external monitor, so she can have more space to work. Since she got home and connected this external monitor she is having KP's, so far as i've noticed, just when she shuts down Parallels, but not always when she shuts it down.

At first i was sure it was the new RAM, but after both tests passed (see above) i am starting to look for another source. Temp is sitting at around 50c-80c max. I have also run Onyx and fixed the permissions.

And now that you asked about the external monitor, could it really be the cause of the KP's (thru Parallels)?

I decided to do the memtest again, it failed one time out of 5 passes, does this mean one of the memory sticks is bad?

I too have the similar problems,really don't know what exactly happening this

To those who have kernel panics, see this article, which explores the same failure message that I was getting, shown below the link.

Engineering at both Apple and Parallels looked at the failure, and concur that this is a hardware problem, likely in the graphics subsystem. Apple needs to improve their H/W test to screen for this.

The failure would occur regardless of whether or not I was running Parallels. Interestingly, this failure (a black screen, caused by a kernel panic) would not happen happen if the computer had only 4 GB of memory. With 6GB or 8GB, it would crash. The computer was a 15" Macbook Pro 6,2 from 2011, with a 2.8 GHz dual core i7 processor. Wiping it clean and reinstalling the OS did NOT fix anything, though I had no crashes for about a day after doing this. In that time I installed Windoze, and I did get 2 bluescreens while installing Apple's drivers. Then I installed MS Word from 2008. Other than that, there was no 3rd party S/W on the computer. Next I installed Parallels 6. When I launched it it crashed. When I launched it again and resized the window, down it would go. Uninstalling Parallels and re-installing it did not fix it either.

Changing the memory to new Apple memory didn't fix it either.

Apple replaced the computer. The ordeal cost me 60 hours of time, so far. Now I need Windows 7, since the new machines won't run XP, or 10.6 either.
