I have the same issue, but not on hardened. Tried for 1-2 hours to send the output to serial console but failed. The text below is what I posted at https://bugs.gentoo.org/show_bug.cgi?id=431640#c8: ###############
Same issue here (same screenshot with qemu-kvm-1.1.1-r1), but not on hardened. Happens with 1.1.1-r3 with a different panic message (not the one mentioned in bug #431444) I fail miserably at "sending output to serial console or file", if anyone would help me there I could provide the entire output of the kernel panic. Below is what I've found out to far: (Tests with qemu-kvm-1.1.1-r1) Analysis: ========= Happens with the following LiveCDs: - Fedora-17-x86_64-netinst.iso: uname -r = 3.3.4-5.fc17.x86_64; image: /LiveOS/squashfs.img - pentoo-x86_64-2012.0_beta1.7.iso: uname -r = 3.4.2-pentoo; image: image.squashfs Does not happen with: - pentoo-x86_64-2009.0.iso: uname -r = 2.6.31-pentoo-r3; image: image.squashfs - (Gentoo) install-amd64-minimal-20120621.iso: uname -r = 3.2.12-gentoo; image.squashfs - systemrescuecd-x86-2.8.1.iso (64bit kernel): uname -r = 3.2.23-std281-amd64: sysrcd.dat Tried installing qemu-kvm-1.1.1-r1 without the 2 patches, no difference. Guess: ====== This seems to happen only with newer guest-kernels (on newer CPUs).
