I have an Optiplex 9020 USFF running the latest version of Catalina. If I attempt to invoke sleep via the Apple menu, the computer attempts to power off, but then the power switch lights up orange, the screen comes back on briefly, and then it reboots. The panic report indicates panic(cpu 0 caller 0xffffff8004414e67): "AppleHDAHDMI_DPDriver::setPowerState(0xffffff801d52b500 : 0xffffff7f86a6b6f8, 0 -> 1) timed out after 10189 ms"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.141.1/iokit/Kernel/IOServicePM.cpp:5296 . . . etc. But this happens even with sleep blocked. I don't think this has anything to do with the AppleALC problem reported in other threads. This seems to be a specific Optiplex-Catalina issue.
I have tried to remove AppleALC.kext and see if that makes a difference.
Is sleep impossible for these hacks?
(On a good note, I finally got my internal BT to work yesterday with some spare time and the latest BrcmPatchRAM3.kext.)
I had a similar problem. I operated the Optiplex 9020 USFF with an HDMI monitor without speakers. There seems to be a freeze when you wake up. you then have to deactivate the hdmi audio out. It worked for me. you have to search the older posts from the thread, there was a similar problem
I'm now on Big Sur with OpenCore. Everything works out of the box except for the audio-out on the back. Even the internal speaker works.
Yesterday, thanks to your contribution, I installed the latest update of BrcmBluetoothInjector.kext. so my Bluetooth works too. wlan worked both under Catalina / Clover and under Big Sur / OpenCore out of the box.
