Hi, my MBA M2(2022, Sequoia 15.1.1) crashes once or twice a week recently.
usually happens when I resuming it from sleep
I've searched on the internet but found no answer
The error message reads:
panic(cpu 0 caller 0xfffffe00291690d0): DCP PANIC - ASSERT!AppleDCPDPTXPowerController.cpp:564 No device added after powering on the rails. HPD=0 - dcpav(27)
does anyone know what the problem is? Much thanks!!

If your Mac restarts and a message appears - Apple Support
The symptoms you describe suggest a hardware fault.
Thank you! I wondered if it was because of ALDENTE
seems not… will contact Genius Bar
It could be. Remove it. It and similarly categorized things can only cause trouble.
Got it. I’ll remove it and see if this works. Thanks again!
