[Help] AppleALC Kernel Panic after Catalina update

Status
Not open for further replies.
I'm having the same problem as well and I opened an issue on Github. Hopefully it'll be resolved soon.
I've commented trying to bring some more info and attention.
 
Confirmed that is fix reboot wake after sleep with 1.2.8 -alcbeta on Catalina 19A583.
Disappeared HDAU@3 AppleHDAHDMI_DPDriver


GA-Z97X-UD7TH Core i7-4770S with IGPU only
Connected through HDMI
It seem need CodecCommander 2.6.3 for no audio after wake.
(RehabMan-CodecCommander-2017-0501.zip)
#Latest version was not work well.
 
I'm having the same issue on my desktop as well. I tried the 1.2.8 release with -alcbeta but I still had the KP.

I have removed the AppleALC.kext for the moment




And I have to add... I'm only having this issue on one of the desktops (the one with the Sapphire RX580+), the other one, with the same ALC codec, is not getting the KP

Your mobo Bios mb_bios_z370-hd3_f13 can find iDisplay Audio Disconnect. However there are no iDisplay in my GA-Z97X-UD7TH Bios.
See this another workaround as below if you have interest.

Thanks!!

I have just modified the DSDT and no more Kernel Panics for me after wake
 
Hi, I just updated to Catalina and everything went smooth expect of Bluetooth and sleep.

I managed to get Bluetooth working by changing brcmpatchram2.kext and adding the injector (found my problem online and solved) but now if my system goes to sleep and I wake it, after 5 to 10 seconds it crashes with the following KP:

Code:
panic(cpu 3 caller 0xffffff800202b747): "AppleHDAHDMI_DPDriver::setPowerState(0xffffff801e31b800 : 0xffffff7f83d87730, 0 -> 1) timed out after 10160 ms"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6110.0.0.121.5/iokit/Kernel/IOServicePM.cpp:5277
Backtrace (CPU 3), Frame : Return Address

I attached my debug files.
Thanks in advance


Boot with -lilubetaall colver argument.
 
Thanks!!
