The bug you are seeing is related to the Linux cmd646 driver which happens to cause an illegal access in the kernel under qemu-system-sparc64. It is most likely due to the lack of IOMMU emulation, however I haven't had a chance to dig into it in much detail yet.
Hi Waldemar,
The bug you are seeing is related to the Linux cmd646 driver which happens to cause an illegal access in the kernel under qemu-system- sparc64. It is most likely due to the lack of IOMMU emulation, however I haven't had a chance to dig into it in much detail yet.
The good news is that if you do want to boot directly from a disk image then you can do it using the virtio drivers with a little work. Take a look at Artyom's blog entry here for more information: http:// tyom.blogspot. co.uk/2013/ 03/debiansparc6 4-wheezy- under-qemu- how-to. html.
Kind regards,
Mark.
