"iMac Pro" kernel crash

I have a new iMac Pro 8core 32gb ram 1tb SSD and Pro Vega 64

(attached are a usb hub, usb audio speakers, usb trackball, thunderbolt 3 raid with a thunderbolt 2 raid chained to it via thunderbolt 3 to thunderbolt 2 adapter)

I am looking for input

Within the first 8hours I had two kernel Panics but now seem ok...my iMac shut off and rebooted by itself...both logs have {"caused_by":"macos","macos_system_state":"running","bug_type":"210","os_versio n":"Bridge OS 2.0 .....

To note my Logitech software wasn't recognizing my trackball but it worked ...after crashes I unplugged and replugged the trackball and the software was able to see it.

Should I be concerned?

iMac Pro (2017), macOS High Sierra (10.13.2), null

So my problem has been temporary solved these are the step I took

1) I erased my hard drive and reloaded mac os

2) i disabled sleep and power nap

3) I removed a sonnet chassis on the the thunderbolt drive that contained a PCIe card ( this seemed to be the solution)

It seems when this card was on the thunderbolt connection to the computer at the same time my la cie hard drive was on thunderbolt crashes occurred frequently. they were never daisy chained and had their own port. Disconnecting either seemed to solve random crashes.The card inside was a universal audio card.

the crashes that happened overnight stopped when I disabled power nap.

4) As others thought the crash is related to daisy chaining I disagree as on another thunderbolt port i have several hard drives daisy chained. It seems certain devices are not playing well together on the thunderbolt data pipe wether or not they are on the same port or not.

I will update if I have any more crashes. The problem is now I can't use my Universal audio PCIe card 😟

I have a higher expectation for a $7K machine!

I agree. This was a pretty awful start for this platform. I’m holding out hope it will happen. The i9 patch gives me reasons to think it can be fixed.

Sorry DustyRo, I get it, was hoping for so much better from the machines. Good luck!

It recalls me the old times of my Firewire 800 audio card: randomly frozen screen and forced restart.

I’ll call AppleCare for a replacement, but I guess this won’t solve the issue :-/

Problem will remain that these machines fail and have kernel panics out of the box with nothing loaded, nothing attached, and running in safe mode.

Yes, it's the exact same panic.

Hi krypttic,

Yes, I am an active participant on MBP2018 Bridge OS kernel panic issue discussions.

My question about the type of kernel panic was to dicoroberto. Thanks for your reply any way.

Just got my replacement. Crashes happening all over again and more frequently.

We need help. Apple engineering needs to give us a diagnosis and game plan!

When the KP occurred here, it was a very hot day, around 36°C or so.

Could it be a thermal issue? It's just my guess...

New iMac Pro. Same issue!

Sad to see Apple has't fixed this issue seeing it was reported back in Jan 18!!

Please tell me how to turn off the T2 security ship?
