My hardware:
The EFI partition (see attachment) was created following https://dortania.github.io/OpenCore-Install-Guide/ with some modifications for OC 0.6.5 (from https://bitbucket.org/profdrluigi/opencorepkg-beta/downloads/OpenCore-0.6.5-RELEASE.zip - I used the debug version which is included in this zip file).
I added the following components which seemed to be right for my hardware setup:
I applied the patches from https://github.com/AMD-OSX/AMD_Vanilla.git (branch: experimental-opencore) to my config.plist and checked it using the OpenCore SanityChecker (https://opencore.slowgeek.com/). All good!
I also did a NVRAM reset.
However, the installation gets stuck at a common place: [PCI configuration begin ].
According to https://dortania.github.io/OpenCore-Install-Guide/extras/big-sur/, the problem is related to RTC issues for Intel's X99 and X299 boards. I don't have Intel, but indeed there's RTC related messages in my Opencore debug log and console output (see attachments):
Google suggested different solutions, just as disabling the above 4G memory option in the BIOS settings or adding ncpi=0x2000 to the config.plist, none of which actually didn't help.
but perhaps these messages are actually not the reason for the kernel panic? I see a couple of other odd things in the logs:
32 CPU cores were detected, half of which have been disabled. I have a Ryzen 7 with a total of 8 cores, even with hyperthreading the number of cores as seen by the OS cannot be more than 16. Further up in the log, there's the following message:
But this refers to the GPU, doesn't it? And a Radeon RX 5600 XT should be supported, according to the documentation. So why is that then?
There's also a couple of ACPI exceptions, but I suppose this is normal, isn't it?
I should also mention that I tried Opencore 0.6.4 as well, but the result is exactly the same...
So I'm puzzled here - what is the reason the installation hangs? Has anyone made a similar experience or has an idea what's going on here? Have I missed anything?
Thanks a lot for any hint!
