I am porting the coreboot to a platform with a new AMD APU, which is close to Kabini and Mullins.

Now the board can boot Ubuntu and Windows 7. But it failed to boot Windows 8.

It crashes at a very early stage, which seems to be Windows bootloader. The debug message of SeaBIOS is attached.

The interrupt routine installed by SeaBIOS still work. We can see handle_13, handle_08, handle_1a are called once in a while.

There is no BSOD. There is only a windows logo on the monitor, without progress ring of Windows 8.

Even the debug version of windows 8 doesn't help, because it crashes before the image is loaded.

Is there any more way to debug windows 8 bootloader?
