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”:

That could actually be a problem with the supplied kernel and/or initramfs if you get a kernel panic without any job context variables being set.

Compare with: https://staging.validation.linaro.org/scheduler/job/168802

Parsed boot commands: dhcp net0; set console console=ttyS0,115200n8 lava_mac={LAVA_MAC}; set extraargs ip=dhcp; kernel tftp://10.3.2.1/168802/tftp-deploy-WglOvx/kernel/vmlinuz-3.10-rc7-amd64 ${extraargs} ${console}; initrd tftp://10.3.2.1/168802/tftp-deploy-WglOvx/ramdisk/ramdisk.cpio.gz; boot

You can also try these images for Debian Stretch:

https://staging.validation.linaro.org/scheduler/job/168680

Example job just as a ramdisk: https://staging.validation.linaro.org/scheduler/job/168807

...

kernel:

  url: http://192.168.0.1:8000/x86-64/bzImage

ramdisk:

  url: http://192.168.0.1:8000/x86-64/rootfs.cpio.gz

  compression: gz

First step is to replace these files with images which work on the x86 DUT on staging.validation.linaro.org

...

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

===

That just isn't going to work. The initrd needs to come via TFTP but this is an absolute path.
