[Qemu-devel] [Bug 1792193] Re: AMD Athlon(tm) X2 Dual-Core QL-64 bug

I try to bisect git version. When I run git bisect bad v3.0.0 it says:
Bisecting: 1298 revisions left to test after this (roughly 10 steps)

Something is wrong, isn't it?

Title:
  AMD Athlon(tm) X2 Dual-Core QL-64 bug

Status in QEMU:
  New

Bug description:
  I upgrade my qemu 2.12.0-2 => 3.0.0-1. After that I can't load virtual 
machine with "-cpu host" option. Full command line is
  qemu-system-x86_64 \
        -monitor stdio \
        -enable-kvm \
        -cpu host \
        -smp cpus=2 \
        -m 1G \
        -vga virtio \
        -display gtk,gl=on \
        -soundhw ac97 \
        -drive 
file=/ehdd/qemu/arch_hw_12_08_2018/arch_shrinked.raw,format=raw,if=virtio
  I have Arch Linux on virtual machine. When I start QEMU, GRUB tries to load 
initial ramdisk and stops. System doesn't load. If I try to start virtual 
machine with "-cpu athlon" option then get the same bug.
  I downgrade back to qemu 2.12.0-2 and virtual machine works fine, system 
loads.
  My processor is AMD Athlon(tm) X2 Dual-Core QL-64.
