Routine crashes even with SIP and Secure Boot Off

Just FYI, I left the enclosure off all night, and there were no crashes.

Sent both requested files via wetransfer

Also, FYI, I turned the enclosure back on before running that sysdiagnose command, and the next time I woke the CPU from sleep, it crashed (after no crashes without the enclosure on).

I'll need some kind of acknowledgement from Apple/OWC within the next week or so, or I'm going to have to return this thing and figure something else out.

Thanks that info will help.

I have your diagnostics files, we will file an Apple bug report with them. I cannot promise how long that will take before we get a response.

I have your same machine in the office and never get kernel panics waking from sleep.

One last idea, lets check basic hardware.
Do you have an alternate Thunderbolt cable to test with?

Try connecting to the other port on the enclosure and a different bus on the iMac Pro? (there are four ports, and two buses, 1-1 & 2-2. Don't do both tests at once, it would be better to know what the cause is, computer or enclosure, if one does not panic and the other does.)

I will try that this weekend.

OK. I think the answer is it crashes only when the Thunderbay is connected, regardless of whether the volume is mounted.

Do you have any old disks around? Could you test if this crash happens only with Apple formatted disks (1 or 2 is plenty) inserted?
It would be appreciated!

I have a 20TB Western Digital as a Time Machine backup that works fine, as well as a G-RAID 16TB (RAID 1) enclosure over Thunderbolt 2. Both have been plugged in and running fine. They're both plugged into a CalDigit TS3 dock, connected via Thunderbolt 3 to the iMac Pro (and were both plugged directly into the iMac before getting that dock).

Is that what you mean?

I'm assuming you mean other drives in the Thunderbay enclosure. I don't have any others I can put in it. The four I put it in are brand new Ironwolf drives, formatted/setup through SoftRAID.

I saw 10.5.2 beta1 was released today. Should I have high hopes that this is going to be addressed in the next version? I've only got a couple of weeks of return window, and right now this is untenable.

10.15.2 won't help.

If you disconnect all other drives, but the Thunderbay, does the crash still happen?

Minimizing the possible causes always helps.

Where did you purchase?

> 10.15.2 won't help.

Am I conversing with two different people?

I purchased it from Amazon.

One person.

I understand the time problem. I am not sure we can hurry a response from Apple, but I will bring this up internally to see what can be done.

I've done some more debugging, and seems that any use of daisy chaining that includes the Thunderbay will crash the computer. If I have the Thunderbay plugged directly in (with the supplied cable), I didn't see a crash for an hour or two.

When I plugged in the CalDigital hub (which only had one USB hard drive and ethernet plugged into it) into the Thunderbay, with the Thunderbay plugged into the iMac, the computer crashed (I'm not sure how long it was up).

When it's Thunderbay > CalDigital > iMac, it crashes.

When it's just the CalDigital, with as much plugged into it as will fit, but no Thunderbay; no crashes.

Excellent clue, thanks.

And it makes sense. Try testing with different port on the enclosure and the dock. (should not make a difference, but if it does, then it helps isolate the triggering factor. In any case, this seems to be an Apple bug, not a hardware bug, even if the hardware is triggering it, there should not be a crash in macOS X

Anything else I do with Thunderbolt works fine though, only when a Thunderbay is plugged in do I get the crashes. Apple bug or not, I can't use this thing right now.

There is no configuration of ports or cables that keeps this from crashing my computer.

Thank you, we will be in touch with our Apple contacts next week and will try to figure out what is causing this.
