It seems to work. No more error messages when gnumach runs in the old qemu. In
the latest qemu, the error messages like "hd0: read_intr: status=0x41 {
DriveReady Error }" still exist.

I thought the error somehow is related to irq as there was an error like "hd0:
irq timeout: status=0xd8". My DDE PCNet32 driver seems to suffer from the same
problem in qemu even though it works well in vmware. I inserted printing in the
interrupt handler in the kernel to check whether interrupts for the pcnet32
device have been triggered but didn't see any. Can I check interrupts in the
qemu side?
