Can anyone help? Kernel Panic (3 times) Panic(cpu 0 caller 0xfffffe002fb26ce0): "AppleT8112DPTXPort(dptx-phy)

I found this thread on github. It's not directly related to that app, but it appears that this has been happening since macOS 14.4 for a lot of people. There are a couple of work-arounds suggested in the thread, including preventing automatic sleeping of displays.

<< panic(cpu 0 caller 0xfffffe002fb26ce0): "AppleT8112DPTXPort(dptx-phy):

AppleT8112 is your Apple silicon M2 (plain) processor. DCP is dimply co-proceesor TxPort is the outgoing data to a display.

MacOS told a display to shut up, and ten seconds later it was still talking and did not acknowledge the command to shut up.

Be sure to change your settings to 'prevent automatic sleeping when the display is off' as detailed above.

Kernel Panic's can be generated by faulty hardware or bad software.

If it only happened three times, then the problem may not be worth chasing.

If it happens over and over....

Disconnect all external hardware like the Samsung SSD 870 EVO 1TB and test.

Then if it continues to happen, start looking at and removing third party software.

Also, for a test disable OneDrive & OneNote.

Might indicate corrupted Spotlight DB.

Manually Rebuilding Spotlight via Terminal

If the aforementioned Spotlight control panel approach doesn’t spur a reindexation of the drive, you may need to initiate it manually through the command line. Open Terminal and use the following command string to do so:

sudo mdutil -E /

This basically asks for temporary super user status, which is why Terminal may ask you for your password (it may not if you’ve used a sudo command recently or are already logged in as a super user or root. The command asks the unix tool mdutil to reindex the spotlight database for everything on the computer, including external drives, mounted disk images, etc. To re-index only for a specific drive, use the /Volumes path. For example, for an external drive named “MiniMe,” the command would look like this:

sudo mdutil -i on /

Rebuilding a drive index can take a long time, so be prepared to wait whether you do it through the System Preference panel or the command line.

If still need be…

Open Terminal and run each of these one at a time

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

sudo will ask you for an Admin password that won't be echoed.

Carefully type your admin password when asked & hit enter.

sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network

killall Dock

sudo mdutil -E /

sudo mdutil -i on /

Rebuilding a drive index can take a long time, so be prepared to wait whether you do it through the System Preference panel or the command line.

Looks good. Do not manual sleep under any condition, it’s totally unnecessary and gets you nothing except mystery problems. Instead, shut the mini for long absences/overnights and/or let the display turn off on timer. IMO, there’s no other solution (but you never know with @BDAqua - stay with him). Good luck!

Could you post a snapshot of your energy saver settings please?

Having the same issue -- probably 5+ times now. Is the prevention of sleeping an issue?

Use the settings exactly as shown below, might fix (display off timer is your choice):

I have had this happen daily for months. Any luck solving the issue?

Apple support keeps having me reinstall OS and refuses to do much else.
