That is most likely dsdt + bios.bin not being in sync.  Simply using
'qemu -bios /path/to/seabios/out/bios.bin' doesn't fly due to qemu using
a non-matching dsdt then.

With qemu/master you can just use 'qemu -L /path/to/seabios/out' instead
and qemu will pick up both bios.bin and dsdt from the fresh seabios
build directory then (and anything else it doesn't find there from the
default locations).

HTH,
  Gerd
