Kernel Panic after BIOS (Asus Z97-pro) upgrade: "unable to find driver for this platform"

Hi,

I just upgraded my BIOS of my Asus z97-pro from the very old version 0801 to 2205.
After the upgrade I had to re-disable secure boot. Afterwards Clover starts up.
However I get a kernel panic: "unable to find driver for this platform"

With an Clover version on my installation USB stick yosemite boots fine.
Clover_Install_log.txt says:
USB: Installer version: v2.3k r3185 EFI bootloader
HD EFI: Installer version: v2.3k r3185 EFI bootloader
I thought the USB is an older Clover version. According the Clover_Intall_log it is the same.

Hence I copied the Clover-config.plist to the EFI partition. This did not fix the kernel panic.

Any idea?
- change some BIOS settings? Most probably yes, but which one?
- change clover version?
- change BIOS version back to an older one?

I did some research. I started with the working usb clover installation. Then I gradually changed the config.plist to my previous one.

The result:

The patch option FixHDA is causing the kernel panic.

Removing it and everything is working again (even the audio).
