I recently bought my new Mac and I'm having trouble, it restarts for no reason ...
panic(cpu 8 caller 0xffffff800b58f8aa): "DSB0(MacBookPro16,1): thunderbolt power on failed 0xffffffff\n"@/System/Volumes/Data/SWE/macOS/BuildRoots/d7e177bcf5/Library/Caches/com.apple.xbs/Sources/IOPCIFamily/IOPCIFamily-428.120.4/IOPCIBridge.cpp:1433
MacBook Pro 16″, macOS 11.5
"thunderbolt power on failed"
It means one of your thunderbolt devices is not getting sufficient power.
Typically, you want to use a USB-C hub that includes a USB-C port just to get power for the computer when it is a notebook/laptop computer, and a second USB-C port and other ports for your other USB-C devices.
Depending on what you are connecting some of those hubs may include ethernet, Displayport, HDMI, SD ports, audio, and USB-3.0 connectors.

I have the same machine and have been dealing with apple support and a half functioning macbook pro for a couple months - recording all my errors between sleep wake failures and these other panics - constant shutdowns. I'm on the last leg of doing another backup wiping out the machine and reinstalling system and doing a selective migration of my information. the ineffective time troubleshooting and doing the tech work is wrecking my productivity time and workload! I expect to buy a fab working tool for $4K+ and what i've spent of the rest of the office apples. But Apple insists on me doing all the work until the last possible evidence is proven it is hardware.
Having these failures after the investment we make to buy this equipment should not happen. I have another MacBook Pro that I have to repair because the screen flickers when using the Radeon card ... but that's another thread. I hope they give you a prompt solution.
Not sure if this makes sense since I only use the Mac battery and usb-c that comes with the computer DIRECTLY into one of the usb-c ports - nothing else connected.
Syrnamue, that should not result in such an error unless there is a hardware problem with the machine or the charger or cable.
Bring it in for service if that's what's happening to you.
