Hello.

I need help to load Linux kernel with rootfs via LAVA (2017.2) job.

My job definition fails with kernel panic “provide correct ‘root=’ option”:

===

device_type: x86

job_name: x86-pipeline

timeouts:

  job:

    minutes: 15

  action:

   minutes: 5

  actions:

    bootloader-action:

    bootloader-interrupt:

      compression: gz

    os: debian

    method: ipxe

    commands: ramdisk

    prompts:

    - 'root@debian:~#'

    - '/ #'

- test:

    timeout:

      minutes: 5

    definitions:

     - repository: git://git.linaro.org/qa/test-definitions.git

       from: git

       path: ubuntu/smoke-tests-basic.yaml

       name: smoke-tests

       from: git

       path: lava-test-shell/single-node/singlenode03.yaml

After then I have added kernel boot options (after metadata section) which lead to “Failed to load file: rootfs.cpio.gz” from iPXE:

===

context:

  extra_kernel_args: initrd=/rootfs.cpio.gz root=/dev/ram0

===

But at the same time I could successfully load it manual from iPXE console:

===

iPXE> dhcp net0

Configuring (net0 7c:05:07:0d:37:c9)...... ok

iPXE> set console console=ttyS0,115200n8 lava_mac={LAVA_MAC}

iPXE> set extraargs initrd=/rootfs.cpio root=/dev/ram0 ip=dhcp

iPXE> kernel http://192.168.0.1:8000/x86-64/bzImage ${extraargs} ${console}

http://192.168.0.1:8000/x86-64/bzImage... ok

iPXE> initrd http://192.168.0.1:8000/x86-64/rootfs.cpio

http://192.168.0.1:8000/x86-64/rootfs.cpio... ok

iPXE> imgstat

bzImage : 6762544 bytes [EFI] [SELECTED] "initrd=/rootfs.cpio root=/dev/ram0 ip=dhcp console=ttyS0,115200n8 lava_mac={LAVA_MAC}"

rootfs.cpio : 43977216 bytes

iPXE> boot
