Hi Hervé, I have this configuration:
Lenovo Z50-70,
cpu: intel i7 4510U Haswell,
gpu: intel hd 4400,
clover r5109, whatevergreen 1.3.8
After I have updated to catalina 10.15.4, if I connect hdmi cable, my laptop goes to kernel panic during boot. If I disconnect hdmi cable it works.
In 10.15.3 it works. I attach my config.plist and kernel panic message.
Can you help me?
Sorry for my bad english
