kernel panic three times since upgrading to 10.14.6

I upgraded to 10.14.6 on July 22. After that, I had a kernel panic on July 25 and twice today. Could anyone help with it?


logs are below.

My panic logs were exactly the same as the ones above (AppleEmbeddedPCIeUpLinkMgmt::_linkInterruptAction(IOInterruptEventSource *, int): \" \"A link timeout has been seen after 100000 microseconds and 49999 iterations.).


Apple returned my Mac (2018 MBP) very quickly and replaced the "Logic Board" (Diagnosis: Kernel Freezes) and "Touch ID Board" (Diagnosis: Cable causing Issue) in it, the diagnostics at the Depot were able to reproduce the issue I assume. Updated to 10.14.6 18G87, no reboots so far and everything works perfectly.


The replacement logic board came with macOS 10.14.4, but the current Boot ROM (220.270.99.0.0) and iBridge/T2 (16.16.6568.0.0,0) firmware version on it. My old logic board had the same firmware versions on it.

Same problem during a Skype video call - happened a bit after 1h into the call.

Well, my Mac with replaced internals just did it again this morning. Was flawless for about a week, this morning it crashed after 5 min. but then after a reboot I was able to Skype without any issue for 30+ minutes. It shows the same error message in the logs as the ones posted here.


Contacted Apple Support again, and we'll see what happens from there.
