It was broken before too, so we are "only" missing a fix, for a rather esoteric use case. And it could very well be that this fix is not needed any more given that seabios got a ahci controller reset so possibly things are working now even without a ahci port reset. > AFAICT it wouldn't be a regression from QEMU's POV. Also not when looking at seabios release tags. take care, Gerd
