Problems with kernel panics when sleeping since 10.6.8

I tried to reinstall 10.6.8 and the problem still is present.

When I enter sleep mode the fan turns on fast. I opened my computer and I can see that my video card fan is actually going nuts.

This leads me to believe its my video card

ATI Radeon HD 5770 and 10.6.8

I'll try one more install of 10.6.8....

I may be better off just disabling sleep mode.

I might just have to use more engery .

Once you've Installed the Combo... leave your Mac on for as long as you can..

It probably wouldn't hurt to do a Permissions Repair and a Restart... Both before and after the Install...

I know some say it is not necessary these days... but...

It looks like I solved the issue (well, at least for myself). Turns out I need to unplug one of the two monitors from the video card before making the machine to go to sleep. I have been doing for several weeks now and no kernel panics since on 10.6.8. It's a pain to have to go behind the computer every time I want it to go to sleep and then re-plugging the monitor after waking it up but it's better than kernel panics, I guess. Give it a try, might help you solve this nasty issue as well.

I am curied of the problem!!! it is fixed!

I deleted my

MAC HD/library/preferences/SystemConfiguration/

com.apple.PowerManagement.plist

com.apple.AutoWake.plist

Thanks!

That is really Good News....🙂

I celebrated to early, it failed again.

It worked fine last night and yesterday.

Just now my computer went to sleep and failed to awaken.

AHH!

😠

Well you can add me to the list. I have been having problems for the last few weeks.

2006 Mac Pro 1,1

8GB Memory

2 x Xeon 4 Core CPU's (forgot the exact model I upgraded to)

1 x 64GB SSD Boot Drive

3 x 1TB HDD Drives

nVidia 7300GT

I use this as a Parallels VM server, so it doesnt sleep, or at least it's not supposed to (Just verified both settings are "Never"). Not sure what is going on with it honestly since it was my primary workstation for years without issue and in pretty much the same configuration (used to have nvidia 8800GT, but sold it since this was going to be a headless server and put the original 7300GT back in). I think it's just jealous of my new 27" iMac. 😁 (Which I am having no issues with at all!)

But seriously, I am running OS X Lion Server on this thing and it still locks up at least once a week at random. I believe I had the issue under Snow Leopard as well. It's hard to remember.

****, it just crashed again while I am writing this! Sometimes I get the kernal panic, other times it just freezes. This time it froze while I was looking at the last kernel panic details. The irony.

I am suspicious of Parallels to be honest, but I have not tried without it. Parallels 7 is now out and I am wondering if I should fire $50 at it and see if it magically got fixed.

I have tried SMC Fan Control and it's keeping the CPU temps between 95 and 100 degrees F (1200 rpm).

I thought it might have been my USB to Serial adaptor, but it crashed even with that unplugged.

I have only 1 display attached and it's usually powered off.

I just disassembled the entire machine this afternoon and gave it a thorough cleaning. That obviously has not helped (wasn't very dirty either) but I did check the CPU's out and gave them fresh thermal paste.

I just ordered 16GB of memory on ebay (because it's cheap, not because I think it's the issue) so it would be nice to resolve this soon.

I don't really run anything other than Parallels build 6.0.12094 and the screen sharing agent (Splashtop Remote v1.5.0.1) on this box. The CPU usage is usually pretty low and I check the temp on the menu bar when the system is locked up and it's usually lower than 100 degrees F. I think that eliminates a thermal issue.

It's not a critical box, so I haven't been very active in getting to the bottom of it. I thought my CPU upgrade might have finally gone kaput, but seeing how you guys are having the same trouble makes me think it's software.

And my kernel panics are mostly the same error on different CPU's:

Sat Aug 13 12:44:19 2011

panic(cpu 1 caller 0x2cd41c): "Machine Check at 0x020bf7f9, trapno:0x12, err:0x0,"

Sun Aug 14 10:33:18 2011

panic(cpu 1 caller 0x2b0571): "TLB invalidation IPI timeout: " "CPU(s) failed to respond to interrupts,

Sun Aug 21 23:10:09 2011

panic(cpu 2 caller 0x2b0571): "TLB invalidation IPI timeout: " "CPU(s) failed to respond to interrupts,

Sat Sep 3 22:30:05 2011

panic(cpu 7 caller 0x2b0571): "TLB invalidation IPI timeout: " "CPU(s) failed to respond to interrupts,

I just updated to Lion.

My computer can sleep again.....(for now).

Since I am grasping at straws anyway, I went ahead and reset the PRAM and SMC to see if it has any effect. Now I wait. The machine normally has 1 Linux VM active at all times.

MacUpdate is telling me there is an update for Parallels 6 that fixes some 10.6.8 issues, but the Parallels Update downloader doesnt seem to know about it yet. Not sure what that means, if anything, for my Lion Server.

Parallels runs great on my i7 iMac.

Having similar issues here but with a MacBook Pro 2010. I upgraded to a SSD (Crucial M4 256gb).. and have a CPU kernel failure and several issue with freezing every so often. I'm not sure if it's Parallels or the SSD (or the memory .. which I upgraded to non-Apple 8gb also).. It can go a few days without causing any problems.. then sometimes it'll just freeze (even while using it).

So having done nothing but reset the PRAM and SMC, the machine has survived for nearly 6 days without a lockup or crash report. It has also been running 2 VM's instead of 1, but still lightly loaded on the CPU. One VM has been continuously connected to a Cisco router console via a USB serial adaptor mapped to it through Parallels.

16:17 up 5 days, 18:18, 2 users, load averages: 0.91 0.98 0.94

Not really enough time to declare it fixed, but my new 16GB of memory arrived today so I need to interrupt the test to install it. Prior to all of this cleaning and resettting, I did run the Apple Hardware Tests with the full memory test option several times (5 times consecutively I think) a couple weeks ago. There was never any indication of a problem. I am installing the memory as an upgrade, not as any part of a repair. I'll post an update next Sunday if it survives all week, or sooner if it crashes/locks up. Fingers crossed! 😕

I have a similar setup and have a Lion disk and a Snow Leopard Disk. My SL HD will run 24x7 no problem. Lion on the other hand will spontaneously reboot without warning or I'll be greeted with a unresponsive black screen and keyboard (no caps lock light when pressed).

I've been following and posted on a blog of a person with a similar issue. Hope Apple can fix it!
