It looks like the guest is rebooting (rip = 0xfff0), probably due to an earlier bug, so the register dump doesn't tell us much. > If I try to run it without kvm: > > qemu-system-x86_64 -no-kvm -cdrom amd64cd-3.1.iso -hda hda.img -boot d > > Then I get a blank SDL window that is entirely frozen (can't even > switch to the qemu monitor).

Can you send .config for that kernel? -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- Take Surveys.
