I've tried with the version compiled from the edk2 HEAD and that also 
fails with -M q35. I've managed to get some debug output via the options 
described in OVMF's readme file and the error is around where initialising 
the graphics card. With q35 it stops with:

ASSERT .../edk2/MdePkg/Library/BaseIoLibIntrinsic/IoLibGcc.c(163): (Port & 3) == 0

This function is IoRead32 and it says the port must be 32-bit aligned. 
I've tried to find what port it tries to access but qemu -d ioport option 
generates no output for me. Any hints on how to use this debug option of 
qemu?
