Recurring Kernel Panics

Lately, I've been experiencing frequent kernel panics. They might happen like 3 times a day, and I'm worried. These kernel panics have been distracting me from my schoolwork, so I would appreciate if I could get help soon. I tried updating the software, freeing up storage, and uninstalling unnecessary extensions. They seem to happen when I put my computer to sleep by closing it. I would hear a noise, and when I open up my computer again later, I would be informed that it restarted because of a problem. I tried disabling sleep-related extensions, but that didn't seem to work. Please help me, as I need my computer for school.

Here's my error report:

< "UPSB(MacBookPro16,1): thunderbolt power on failed >

I'm concerned that the issue may be related to hardware not software.

Uninstall all third party apps that are Cleaners/Optimizers/Anti-Virus/VPN

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

(get at least two-three rounds of the chimes when holding the NRAM Reset)

Can you run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.

I just wanted to chime in and say that I am having the same issue on two Late 2019 MacBook Pro 16" machines. I have one for work and one for home use. Both machines are identical (32GB, 1TB) except for one is i7 and one is i9. Both started crashing after I updated to Big Sur 11.6. I upgraded my personal Mac last week, and that is when the crashes started. I was worried about a hardware failure, so I decided to upgrade my work mac this morning. It just crashed.

I've tried the NVRAM/PRAM reset with no luck.

This is the second major Big Sur bug I've encountered this year. The first one was the external display issue that ran them at 30fps. I am disheartened with Apple that this type of production breaking bug is happening again. Remind me why we pay so much for these computers again?

Disconnect all external devices from the laptop to see if one of them is causing your problems. The Kernel Panic log you provided mentioned "thunderbolt power on failed".

Also see if you have any more Kernel Panic logs so we can see if there are any patterns. The Kernel Panic log file names begin with "kernel" and end in ".panic" and can be found in "/Library/Logs/DiagnosticReports" if they exist (they don't always get saved).

You can also look for possible software issues by running EtreCheck and posting the report here using the "Additional Text" icon which looks like a piece of paper. Just make sure to select the "Share" option in the EtreCheck app and select "Copy Report", then paste it here with the "Additional Text" feature.

For hardware-related issues, you can arrange a service visit at the Genius Bar at a nearby Apple-owned store, are (but you need an appointment).
