Kernel Panics with Adobe Photoshop on macOS Big Sur Continue

I can’t seem to get clarity from Adobe if this is an Adobe bug, or an Apple bug.

I am hesitant to blame it on Adobe, for two reasons: (1) I spend a lot of time in Photoshop (thus increasing the likelihood of it seemingly being involved), plus it exercises the hardware substantially, and (2) I don’t know how an application can cause a panic from “NMIPI for unresponsive processor”, since that’s a hardware-level thing (not software).

Still, the majority of kernel panics I’ve had have been in Photoshop and generally when I open a lot of raw files at once. But also at other times.

No change in moving to macOS Big Sur—this happened on macOS Catalina also. It has been a problem ever since July 2020 or so, maybe August. If I had to guess, I’d say it relates to one of Apple’s security updates back then.

I thought it might be related to the GPU, but then why an unresponsive CPU?

Symptoms

  1. Working in Photoshop, the machine goes unresponsive—no mouse, no application switching.
  2. After about 20 seconds, the screens blank and the machines shuts off.
  3. Pressing the power button, the Mac Pro comes up with the usual “Your computer shut down unexpectedly... press any key to restart”. The usual kludge that means “we at Apple can’t get our stuff to work reliably”.
  4. Pressing a key and rebooting, the computer comes up. Usually I have to unplug and replug USB devices like keyboard and mouse as they do not work at first. Then I login, but the 2nd display is missing. Often I have to reboot again to fix that.

This whole clusterfuck takes down all work in progress as well as a 10-minute cycle just to get operational again. And because I might have lost a dozen open files, I have to start over sometimes, which can be a half-hour hit.

It can also desroy the file system on backup drives, so I like to keep them turned off.

So infuriatingly unacceptable.

Maybe it’s a hardware error, but when I tried to run Apple’s hardware test, that hung on me. And tearing down my entire work environment to wait a week for Apple service is just a nightmare proposition.

AFAIK, the TLB thing refers to “translation lookaside buffer” and relates to virtual memory mapping on the CPU. Suggesting a CPU bug or a macOS implementation bug.
