The command line to run qemu is as follow: qemu-system-x86_64 -enable-kvm -kernel /pkg/linux/x86_64-randconfig-n0-02271436/gcc-5/21bb45b419243ee4d9d74f1d1f97164fbfc481c3/vmlinuz-4.5.0-rc2-00420-g21bb45b -append 'root=/dev/ram0 user=lkp job=/lkp/scheduled/vm-client3-openwrt-ia32-2/rand_boot-1-openwrt-i386.cgz-x86_64-randconfig-n0-02271436-21bb45b419243ee4d9d74f1d1f97164fbfc481c3-20160228-50262-1pt11n1-0.yaml ARCH=x86_64 kconfig=x86_64-randconfig-n0-02271436 branch=linux-devel/devel-hourly-2016022600 commit=21bb45b419243ee4d9d74f1d1f97164fbfc481c3 BOOT_IMAGE=/pkg/linux/x86_64-randconfig-n0-02271436/gcc-5/21bb45b419243ee4d9d74f1d1f97164fbfc481c3/vmlinuz-4.5.0-rc2-00420-g21bb45b max_uptime=600 RESULT_ROOT=/result/boot/1/vm-client3-openwrt-ia32/openwrt-i386.cgz/x86_64-randconfig-n0-02271436/gcc-5/21bb45b419243ee4d9d74f1d1f97164fbfc481c3/0 LKP_SERVER=inn earlyprintk=ttyS0,115200 systemd.log_level=err debug apic=debug sysrq_always_enabled rcupdate.rcu_cpu_stall_timeout=100 panic=-1 softlockup_panic=1 nmi_watchdog=panic oops=panic load_ramdisk=2 prompt_ramdisk=0 console=ttyS0,115200 console=tty0 vga=normal rw ip=::::vm-client3-openwrt-ia32-2::dhcp drbd.minor_count=8' -initrd /fs/sdb6/initrd-vm-client3-openwrt-ia32-2 -m 192 -smp 1 -device e1000,netdev=net0 -netdev user,id=net0 -boot order=nc -no-reboot -watchdog i6300esb -rtc base=localtime -drive file=/fs/sdb6/disk0-vm-client3-openwrt-ia32-2,media=disk,if=virtio -drive file=/fs/sdb6/disk1-vm-client3-openwrt-ia32-2,media=disk,if=virtio -pidfile /dev/shm/kboot/pid-vm-client3-openwrt-ia32-2 -serial file:/dev/shm/kboot/serial-vm-client3-openwrt-ia32-2 -daemonize -display none -monitor null The root file system used for test can be downloaded in: https://github.com/fengguang/reproduce-kernel-bug/tree/master/initrd The one used for test should be yocto i386 root image.
