When I change the IDE controller from IDE to AHCI the WinPE images freeze at:

emulating drive 0x81
entering bootmgr.exe with parameters at 0x02a390

...

I am guessing this is a hardware related problem but maybe you guys got an idea?
The machine is a POS (Senortech) with an Aptio BIOS and a Realtek B01 D00 NIC.
When i set the protocol on IDE everything works flawless.
thanks in advance!

It sounds like a BIOS bug. Have you checked for a BIOS update?
