Recurring Kernel Panics: Mac Pro 2009

[sgentile92]

Hi All,

I've got a pretty heavily modified Mac Pro 2009 (flashed to 5,1) with upgraded processors, RAM, video card, USB 3, SSD, the whole 9 yards. Since upgrading, I’ve been getting near constant kernel panics. It used to be when I was in Photoshop, Lightroom, Illustrator, things like that. Then it started to be seemingly random (just mail and safari open). Then it started to be 80% of the time that I it up from sleep mode. Recently, it panics after waking from sleep mode, restarts, I log in, and it panics again. Sometimes it loops like that 2, 3 or 4 times. Sometimes it does it once. I can’t for the life of me find the rhyme or reason.

I would really appreciate any help I can get here. My brand new MBP was stolen a couple years ago, I got my hands on this 2009 MP, and really got invested in making it a kick-ass machine. I really can’t afford a new computer at this point so this is what I’ve got to work with.

Below is the most recent kernel panic that happened after it panicked twice. I saved some other panic reports that I can post if that helps.

UPDATE: Kernel panicked as I tried to hit the submit button on this post. I can upload that too if that will be helpful.

This would point to a network issue:
• captiveagent detects when you're on a captive-portal network, it does this by checking for known-content domains apple controls. • helpd is the daemon that connects to Apple's online help docs.

The only problems I have had with hard to diagnose crashes were disk related with very few relevant messages.

 

[kohlson]

I am not certain what "9 error-reporting banks" means, but that can't be good. It may a problem related to the CPU swap. Have you run AHT?

Model: MacPro5,1, BootROM MP51.0084.B00, 12 processors, 6-Core Intel Xeon, 3.33 GHz, 18 GB, SMC 1.39f5
Graphics: NVIDIA GeForce GTX 970, NVIDIA GeForce GTX 970, PCIe

There are 6 firmware upgrades after MP51.0084.B00. It's the first firmware from the High Sierra era, pre-Meltdown/Spectre microcode updates.

You should upgrade to at least MP51.0089.B00, read the first post of these two threads:

• MP5,1: BootROM thread | 140.0.0.0.0
  
• MP5,1: What you have to do to upgrade to Mojave.

Machine Check + X error-reporting banks points on RAM issue, but it may be affiliated with CPU(s) as well, since memory controller is in there.

 

[visusest]

I was getting random system hangs (beach ball progressing to black screen) that I couldn't figure out. Found a suggestion for turning off "Allow user to reset password using Apple ID" under Users and Groups in System Preferences. That was about a week ago and I haven't had an issue since. YMMV but worth a shot.

 

[666sheep]

worth a shot.

Waste of time and wrong direction unfortunately.

@haralds How would I test if it's a network issue/if that is the problem, how would I resolve it?

@kohlson I just ran AHT and it came back clean—no issues. I ran the normal one and the more extensive one that took over an hour. Would that mean seem to rule out a hardware issue?

There are 6 firmware upgrades after MP51.0084.B00. It's the first firmware from the High Sierra era, pre-Meltdown/Spectre microcode updates.

@tsialex Thanks for the info. I didn't realize that I had to manually update the firmware. One of those links said that prior to performing the update, I have to insert the original GPU and connect a non-4K display. It also looks like in the new firmware, there are GPU compatibility issues—I have a NVIDIA GeForce GTX 970, flashed by MacVidCards, will I have a compatibility issue?

Machine Check + X error-reporting banks points on RAM issue, but it may be affiliated with CPU(s) as well, since memory controller is in there.

@666sheep Man, that's what I was afraid of. The one constant between all the panic reports are the error reporting banks message. I ran AHT and it didn't come back with any issues. Is there another test I can perform to try to zero in whether it's a RAM or CPU issue? I did performed the "yes" stress test described here on the 12 CPU cores, and nothing crashed. Would that indicate a RAM issue?


I really, really appreciate everybody's help with this. Thanks everyone

You can't upgrade to Mojave with NVIDIA GPUs newer than Kepler, no web drivers yet, but you can run 140.0.0.0.0 with 10.13.6, my main Mac Pro runs 95% of the time with this combo.

 

[tpivette89]

I would also lean towards one of your CPUs being defective. I've had kernel panics that were directly related to a bad CPU.

Take out CPU B as well as it's related heatsink and run the machine again. If nothing changes, take the CPU that was in socket B and install it in socket A and run the computer again. If things work as normal in either scenario, then you know which CPU was giving you the problems.

 

[verdejt]

I'm running a true 5,1 with a NVIDIA GTX680 and on Mojave with no issues. My machine is at 140.0.0.0. I have had no problems at all. I am running with the native Apple Driver and not the NVIDIA one as it hasn't been released yet. I have had no issues. Keeping my fingers crossed.

 

[kohlson]

Machine Check + X error-reporting banks points on RAM issue, but it may be affiliated with CPU(s) as well, since memory controller is in there.

My first thought. But I believe there are only 8 RAM banks, and the error message was for 9. And the message was in the "CPU section." But I am the first to admit that I know essentially nothing about an such an error - other than it's not good.
If all the memory that's there now was there before the CPU upgrade, and it's Apple original and it worked, my guess is that it's not the memory. But this is "down-spec" memory for X5680. Should be 1333, and it's reporting as 1066. From what I understand this shouldn't be a problem.
There is a lot of posters who seem to report issues after installing CPUs and not tightening them in properly. In most cases, proper installation/tightening can resolve - the cMP is fairly resilient. But over/under tightening, and improper thermal paste application, seem to cause issues. So you may want to re-install.
The AHT, in my experience, isn't always helpful. My MBP, which was consistently failing to boot in an Apple Store tech's hands, passed the AHT.

I tried following the instructions that you linked me to on how to update the firmware to 140.0.0.0.0 but I'm a little lost. With my original graphics card installed (Radeon HD 4870) I can't run the installer specified in the below part of the instructions because I get the message that mojave requires Metal capable GPUs:

• manually trigger the install with 10.14.3 RecoveryHDMetaDmg.pkg. Instructions in this post, use the current RecoveryHDMetaDmg.pkg (~450MB download).

Is there another way to trigger the firmware update?

General update: Reinstalling the original GPU didn't change anything, so I suppose that's one thing that can be ruled out. I've ordered the hex tool needed to remove the heat sinks from the CPU so that I can test those next.

Thanks for bearing with me. I really don't want to give up on this thing!

Thanks for bearing with me. I really don't want to give up on this thing!

HD 4870 is not a METAL supported GPU, you can't upgrade from MP51.0089.B00 to 140.0.0.0.0, but you can do the first part with it if it's an original Apple GPU.

You first upgrade to MP51.0089.B00 with a Mac EFI GPU, then you remove the card and install a METAL supported one to upgrade from MP51.0089.B00 to 140.0.0.0.0 - this one needs to have native drivers, so no NVIDIA GPU other than Kepler, newer ones don't have drivers.

You can't do the second firmware upgrade with a NVIDIA GPU newer than Kepler.

Ah ok. That makes a bit more sense. I think I got confused with the naming conventions for MP51.0089.B00 and 140.0.0.0.0 — they're both firmware updates, right?

How do I trigger the MP51.0089.B00 update?

Yes, both are firmware updates, 140.0.0.0.0 is the current one, and you can trigger the upgrade to MP51.0089.B00 with the full installer of 10.13.6 from the Mac App Store.

You are asking things that were answered into the two posts that I linked to you. Please read both again.
