Kernel Panics in 10.7.4

Just logging my own experience. Kernel panics every morning since installing 10.7.4. iMac 21" purchased September 2011. I have reset the SMC according to Apple instructions, and no love. I'm downloading the 10.7.4 combo updater to see if that will help, but after reading these comments, I'm not so sure it will.

Considering stepping back to 10.7.3 with Time Machine, but am not entirely sure how to do that.

If you want to roll it back to 10.7.3 you will need to reboot into your recovery HD (restart and hold down the option key after you hear the boot chimes). Choose Recovery HD and then select Restore from Time Machine. Choose your most recent backup of version 10.7.3 (for example, mine was from May 9 @ 830AM). It took my system a few hours to restore from my external drive, which is connected via USB directly to my MacBook. Good luck!

Start the machine up and hold down the apple command and R key. Make sure you have an ethernet connection to the web. It will take a fair amount of time but it will boot the machine in recovery mode using the Apple recovery server via the web. Have your Time machine HD connected prior to starting. You will get a window with several options including doing a restore from Time Machine, When you select it you will get a list of OS available to restore from.

It took me about 7 hours to restore 400 GB, 1.2 Million files and 400K plus folders.

Good Luck.

Thank you!

Ross, here are the instructions and is the only reported solution is to roll back to 10.7.3. I was also contacted by Apple Senior Tech and sent logs, unfortunately I had already rolled back prior to sending logs.

However, if you are still on 10.7.4, I have a suggection to see if it works or not. Try removing the third party plists from the HD/Library/LaunchDaemons & LaunchAgents folder (keeping the com.apple... ones)

I am curious because once i had rolled back to 10.7.3, I continued to have Kernal Panics until I removed the plists mentioned above, now eveything is good on 10.7.3.

Please someone try it on 10.7.4 and post the results.

Just heard back from Sonnet support, and they said to remove the System/Library/Extensions/SonnetAHCI.kext file (mine was actually named a little different), as it's not needed after 10.7.1, and is known to cause kernel panics with 10.7.4.

I also had a SiliconImage3132.kext file in the same directory, probably from an older esata expresscard adapter, so I removed it, too.

Everything works fine now.

just restored back to 10.7.4 and removed all non Apple plists from Library/LaunchDeamons and Library/LaunchAgents. The only one left is com.apple.remotepairtool.plist. However, after restart, 5 minutes in, my MBP 6,1 crashed the same way it did before. Safe mode works still fine.

While I'm at it, any other ideas what to remove? ;-) Im desparate enough to try it ;-)

Your best bet on regaining stability is to go back to 10.7.3.

Does anyone know a way to roll back to 10.7.3 without restoring from a TM backup? Wondering if there is a 10.7.3 installer that I can run, but I don't know if that's supported.

I have not had any kernel panics but my early 2011 MacBook Pro has had issues waking from sleep under 10.7.4.

Thanks,

Stacy

Agreed. I have not had a KP since reverting to 10.7.3

I stand by what I said several days ago. Nothwithsatnding the fact that millions of users have updated to 10.7.4 without issues, for many of us, the update is buggy and Apple seems to be waking up to this fact.

I expect they will release a fix in the near future.

I did a clean 10.7 install and downloaded and installed the 10.7.3 combo update.

That took care of the ongoing KP problem for me since updating to 10.7.4.

Thanks medoras. I may need to do that, I'm downloading the 10.7.3 combo now.

I have had a ten-fold increase in the number of kernel panics since updating to 10.7.4. 8-10 in a day. When I ordered my 12 core tower last December it came with 6 gigs of Apple memory. I decided to add 32 gigs of memory from Kingston. The install went well and the memory check came back positive. But within days I was having several kernel panics a day. I ran a little experiment where I created several different combos of only 16gigs of memory with the four 8gig modules. With only 16 gigs of memory the kernel panics went from 4-5 a day down to 1-2 every two weeks. Not ideal, but I didn't believe it was a memory hardware problem. Now after the 10.7.4 update I replaced the 16gigs of Kingston memory with the original 6gigs of Apple memory. Now the kernel panics average 1-2 every day. I'm just not buying that it's memory hardware related, unless the OS and how it acts with the memory is corrupt.

I spoke with Apple this afternoon.

It's a software problem. Apple is aware of it and is working to address it.

Hang in there.

After a few days of no problems on 10.7.3 the crashes have started up again. Anyone else having problems after going back to 10.7.3?
