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: minutes: 5 bootloader-retry: minutes: 5 bootloader-interrupt: minutes: 5 extract-nfsrootfs: seconds: 90 priority: medium visibility: public

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}

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
https://staging.validation.linaro.org/scheduler/job/168802/definition
You can also try these images for Debian Stretch:
https://staging.validation.linaro.org/scheduler/job/168680
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.
