Since installing Catalina, I've been experiencing kernel panics when I leave the machine idle (2019 MBP 15 with Vega20). I had no such issues under Mojave. There's a thread here documenting many others experiencing similar behaviour: https://discussions.apple.com/thread/250717203?page=77
I'm quite surprised to see there are no similar threads or reports in here.
I've been submitting sysdiagnose reports via Feedback Assistant consistently since this began. Having installed 10.15.4 beta 2 last night (with great hope for resolution as always), it took only a few hours before the system bombed again.
Looking at the case that I've been submitting my data under, I can see that under 'Resolution' there's now a text that says 'Investigation complete - Change required from 3rd party'. But there's been no correspondance in my direction about this. What 3rd party change is required here? Is there something I can do to move this along?
Is there any point in submitting my data any more? I've been doing it in the hopes that a fix would come from Apple, but this status update suggests that Apple believes the problems lie elsewhere?
