I have an Asus K501LX laptop that I decided to test with the Vgal's RC2 build of ReactOS 0.4.7. I have the model with the i5 5200U and a 1TB HDD.
It loops on the USBH_Wait part for each of the ports that it finds, then crashes with a 0x0000007b error code.
Cannot boot from CD-ROM, because this laptop does not have it. Also cannot grab a log from the serial port. I attached the log from the Screen mode instead. The Debug mode hangs on swenum.sys, regular mode results in a BSOD. The xHCI controller is disabled. CSM mode enabled.
Attached the crash, backtrace and the looping part. Please tell me if there is more information needed.
