Kernel panic after waking up: DCP PANIC - ASSERT!AppleDCPDPTXPowerController.cpp:538

“If you think clicking the button to send the Kernel Panic to Apple is the same thing as what HWTech detailed in the post, you are sadly mistaken”

I never said or thought so. Where did you get the idea of that?

I'm seeing the Genius Bar tomorrow in Beijing, MacBook Air, M2

panic(cpu 1 caller 0xfffffe002f786ea8): DCP PANIC - ASSERT!AppleDCPDPTXPowerController.cpp:538 No device added after powering on the rails. HPD=0 - dcpav(27)

ASSERT!AppleDCPDPTXPowerController.cpp:538 No device added after powering on the rails. HPD=0

Is there any advice in case my Genius has no idea about this? Something I can tell the "Genius"?

Macbook Air M2, 2022

Same issue start happening just after updating Sonoma.

Never happened before. And Still happening now.

I did all apple support guidance, even wiped all HD (factory reset - the last "solution") and still happens, updated to last macOS, STILL happens.

The worst of all is that when a kernel panic like this happens, its a HARDWARE issue, so Apple broke our Apple's macbooks.

I don't know why, but your Sonoma broke down your, our, my computer/s you have to recall or fix this.

Kernel panic happens just when macbook goes into sleep mode and when it tries to wake, BOOM shuts down.

These are NEW computers. I dont know but we have to do something. We are apple clients and they are the responsible of this. You broke our computers with your macOS update. You have to fix it.

WTech - Thank you so much for your expertise and advice. I'm experiencing this issue on startups and a few times when the display wakes after having gone to sleep.

Last night, I made the mistake of telling the Genius Bar tech that folks on the web were saying "Replacing the display and the lid angle sensor would fix the problem." That was the wrong approach with this tech person. Even when her diagnostics indicated a problem with the lid angle sensor, she just ran her diagnostics a second time and it came out clean.

I'm thinking about waiting for awhile before taking my laptop into a Genius Bar for a second time, hoping that in another few months Apple Support will have a better handle on the problem and I'll have a lot more documentation that will be helpful.

Is there any issue with not getting this repaired sooner?

I've been having this issue for about a year and literally no clue what to do about it. I don't have time to be without my laptop whilst they wipe it and tell me it's all fine. This is what I'm getting, there seems to be no rhyme or reason for it. I do use an external monitor but it happens without it, too. I can go a week or two with it happening once or twice, then it'll happen four times in a morning, as it has today. I don't do anything differently. A Mac was a huge investment for me, so it's disappointing.

Just checking up is the device still error free?

@Utania Is that something only the Apple Store staff can do? Or do you mean that the genius reset the PRAM?

No it is not still error free. The kernel panics returned after a week or so. Now it happens every few days.

There is no PRAM on the M series processors.

I submit an error report every time a panic occurs. Otherwise, how exactly do you contact Apple directly?

What perhaps are you talking about? I already told you we have notified Apple about the issue. There is no perhaps here.

I know for a fact that Apple store genius bar has seen the issue many times. It’s Apple’s choice whether or when they want to act on it. I hope it is clear.

I am experiencing the same issues. It just started happening. Can I bring it in for a replacement?

I'm getting the same issue pretty regularly. I'm going to bring it to the Apple Store/Genius Bar. I'm also reporting it, as I assume others are.

Hi, I have the same issue. Could you please link the video?
