Thanks a lot! I will definitely get rid of the keepsyms=1 flag.The mDNSResponder is suggestive of it being network related, but beyond that, it's difficult to guess. Boot arguments can sometimes be a cause. keepsyms=1, particularly, while useful for debugging, can be a potential candidate for all kinds of random crashes. shikigva=80 might be worth trying (instead of 40). Is hardware acceleration enabled on your GPU? If not, maybe that's a contributing factor.
That said, an ill-chosen device-id could might still be the culprit. Maybe try F3150000 or F2150000.
When it comes to the iMacPro1,1 + AMD dGPU settings, I doubt that shikigva=80 is correct.
I don't have an iGPU, it is disabled, as I'm using a i7-11700k, which has an Intel UHD Graphics 750 (iGPU) that is not supported by macOS at all. I'm using an AMD Radeon RX 560 4GB (Polaris chip), WhateverGreen.kext, SMBios iMacPro1,1, shikigva=40 shiki-id=Mac-7BA5B2D9E42DDD94, two displays (1x HDMI, 1x DP) both run smoothly at 4k@60Hz. In the BIOS (Version F4) "Internal Graphics" is set to disable.
Netflix, Amazon Prime Video, Apple TV+ work fine in Safari (and all other browsers)
GPU-based hardware acceleration is working too:
./VDADecoderChecker Hardware acceleration is fully supported
VideoProc Converter H264 4k firstname.lastname@example.org Available HEVC 4k main@auto Available
According to Dortania's guide: shikigva=40 shiki-id=Mac-7BA5B2D9E42DDD94 are the recommended settings for my AMD RX 560 (Polaris chip) and my iMacPro1,1 SMBios. What am I doing wrong?
