I tested the kernel from the netinst mini.iso. It is still affected. How to reproduce: 1. Install KVM (userspace tools) 2. load KVM kernel modules (modprobe kvm-amd or kvm-intel) 3. Lauch KVM with a kernel: $ kvm -kernel /boot/vmlinuz -append "console=ttyS0,115200n8" -m 1G -cpu phenom,model=9 -serial stdio This should give you the kernel boot output directly on your terminal. Working kernels will crash while looking for their root device, this is OK (since there is none). Failing kernels will panic earlier with the above crash dump. Another option is to boot the ISOs directly: $ kvm -cdrom mini.iso -cpu phenom,model=9 This will currently crash with the latest netinst .iso, model=8 will work. Please note that model=8 is not a possbile workaround, since -cpu host will imply model=9 on an AMD Magny-Cours machine. The bug fix is already in mainline 2.6.32.12, although I believe this release has introduced another bug :-(
Jeremy, is there a binary kernel .deb I can test? I will build a kernel from source as soon as possible and will confirm if the proposed fix solves the issue. -- kernel crash under KVM when on AMD Magny-Cours https://bugs.launchpad.net/bugs/556480 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
