Reboot when my PC wakes up after upgrading to Catalina

Recommended Posts

Hi MaLdOn,

Crash and reboot still occurs after using your new DSDT.aml. It seems the crash caused by audio driver.

panic(cpu 0 caller 0xffffff801e8290b7): "AppleHDAHDMI_DPDriver::setPowerState(0xffffff8043665300 : 0xffffff7fa01a1730, 0 -> 1) timed out after 10158 ms"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.11.26/iokit/Kernel/IOServicePM.cpp:5302
