Hi Jiří,
I found out that after 645d38325f770af3d73b15f6b1c95d0c2f9de91b
you cannot create or read GPT disk labels. Some assertions fail
in pci-ide.c, the diff bellow fixes it (probably just typos).
There was no conflict with my changes, so I pulled upstream and
then committed the new changes, and just now I found out that it
is not possible to create GPT labels.
