Touchbar not working and panic after sleep mode

Hi, the touchbar on my Macbook M1 2020 Modell A2338 isn't lighting up anymore. It's still functional but I can't see it. At the same time I get the same error every time it goes into sleep mode. The first line starts with:

panic(cpu 0 caller 0xfffffe0030c88a8c): "virtual IOReturn ADPParamFIFO::programFIFO(IOMemoryMap *): ADP FIFO still busy after 1000ms" @ADPParamFIFO.cpp:263

I updated to Sonoma 14.3.1, tried to disable it, killed/restarted the process in the activity manager without any change.

Other people had the same problem here https://discussions.apple.com/thread/254571256?sortBy=best

I wonder if there's an alternative to changing the hardware. Did anyone have the same issue or perhaps a fix?

kind regards,

Max

MacBook Pro 13″

On the M1— if a SafeBoot Use safe mode on your Mac - Apple Support will not sort your issue—it typically indicates a hardware issue.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment

Thanks for the quick reply! just safebooted, unfortunately didn't solve the issue. I live on an island and the authorised dealer will probably sent it in for diagnostic. If it's most likely a hardware issue it will be possibly expensive since I don't have any warranty. So my next step would be to give it to my local computer repair shop to change the touch bar

My 2022 MacBook Pro M2 is doing the same thing. So frustrating.
