WEG: IsTypeCOnlySystem var routing failed in Mac OS Recovery environments, which results in kernel panic #1472

Closed Ubsefor closed 3 years ago

Ubsefor commented 3 years ago

Issue persists after this commit on Kaby Lake Refresh laptop systems, only in Recovery environment, actually panics at boot process thus preventing OS update/install

Example of this and actual boot log (photographed) can be found at reddit post

Will try to collect more precise kernel logs later. EFI.zip – EFI configuration panic.log – Mac OS log after booting into OS normally

You use Automatic, but Generic is empty.

It is not empty but purposely removed before uploading to GitHub. Everything of PlatformInfo configuration is actually present

Dear @Ubsefor, as @vit9696 and @zhen-zen stated in issue #1471, it seems that the kernel panic is caused by AppleBacklightSmoother. Try removing it and see if you no longer experience a kernel panic.

You shall provide panic log with boot-arg keepsyms=1 https://github.com/acidanthera/bugtracker/blob/master/.github/ISSUE_TEMPLATE/bug-in-opencore-or-kext.md

There is actually no need to maintain this issue any longer as it is the problem not with WEG, but with AppleBacklightSmoother kext by hieplpvip. As stated in above reply – I need to remove BacklightSmoother as it works perfectly fine without it. Will possibly update my opened issue at the author’s repo.

So I guess it is solved for now.
