Config file:
	https://github.com/groeck/linux-build-test/blob/master/rootfs/x86/qemu_x86_pc_nosmp_defconfig

Error log:
	http://server.roeck-us.net:8010/builders/qemu-x86-next/builds/44/steps/qemubuildcommand/logs/stdio

You can find the root file system used for the test as well as the test script at
	https://github.com/groeck/linux-build-test/tree/master/rootfs/x86

There isn't really an error message, though - the boot stalls until the controlling daemon
kills the qemu session.
