Crashing with Kernel panic i2c3

crwdns2934249:0crwdne2934249:0:

Hi,

my Macbook Pro 16 (2019 Modell) is randomly crashing with the same kernel panic (i2c3::_checkBusStatus Bus is still in a bad state; see below). It started a few weeks ago. At first, the built-in camera didn't work anymore. The system report/profiler just shows a question mark as a serial number:[br]

Produkt-ID: 0x8514[br]
Hersteller-ID: 0x05ac (Apple Inc.)[br]
Version: 2.01[br]
Seriennummer: ?[br]
Hersteller: Apple Inc.[br]
Standort-ID: 0x80200000

So I guess the failure of the camera is somehow related to the kernel panics. The Macbook otherwise works flawlessly, sometimes running for a few days, sometimes only a few hours. The kernel panics are quite random and I have not managed to reproduce them somehow.

***What I did so far:***[br]
- Reflashing T2 chip with another Mac and the Apple Configurator[br]
- Resetting basically everything (SMC, NVRAM, etc.)[br]
- Reinstalling MacOS

***Does anyone have any ideas what I can do to make the kernel panics stop? If the camera would work again it would be a bonus, but I don't really need it.***
