Hi, I'm using kernel 3.3.0 on one of my VMs and recently it oopsed in ext4 during startup. Before this crash, I did a package update, followed quickly by a reboot. Things went wrong early enough in the boot process that there are no log entries of the system's startup. Yet the fact that it crashed at 12 seconds is weird -- usually this machine boots in under 3 seconds. Strangely enough, after another reboot, things were OK again. I'm using Arch Linux with systemd, x86_64 VM under QEMU/KVM. virtio storage using QEMU's "threads" I/O mode. ext4 with the only mount option "noatime". Here's a picture of the oops: http://ompldr.org/vZDNnNg Since all I have is this screenshot, I'll have to type in the stack trace. The oops message itself was lost thanks to kernel's brilliant debugging tools (Shift+PgUp didn't work).
