I was updating a Fedora Core 6 VM using pup. I can't say exactly what it was doing, because I was working on something else at the same time, but it was near the end of the update process, because it only offered one update on the next boot. While it was updating, I got the following Oops, and the Qemu/KVM process died:
Unable to handle kernel NULL pointer dereference at 0000000000000040...

"run once with qemu and disable the grub bootsplash in the grub config"
Er, I wasn't running grub. It was trying to run ISOLINUX, which doesn't have a bootsplash. Perhaps you were referring to my other bug, which involved not being able to run 32-bit programs on a 64-bit guest kernel? In that case, the probelm isn't real mode, since it was running under Linux; any 32-bit program causes an...

It happens when the ISOLINUX bootloader tries to run. With KVM on, Qemu crashes before the ISOLINUX prompt appears; with KVM off, Qemu gets through ISOLINUX and boots from the CD.

I have tested in several versions of KVM:
kvm-9: Qemu dies at Grub with "exception 13 (0)\nAborted", and dmesg says "kvm: msrs: 6".
kvm-12: Qemu dies at Grub with "exception 13 (0)\nAborted", and dmesg says "emulation failed but !mmio_needed? rip a45 f4 eb fd 89" and later "kvm: msrs: 6".
kvm-13: Qemu refuses to use KVM "kvm kernel version too old\nCould not initialize KVM, will disable KVM...
