[Starlingx-discuss] Duplex: Controller-1 Kernel Panic

Mon Apr 29 18:25:07 UTC 2019

Hi Marcel,

We don't currently have a mechanism to allow a user to add arbitrary kernel parameters to the installation boot cmdline.

In order to test to see if adding this parameter resolves your issue, you could modify the /pxeboot/pxelinux.cfg/ file that corresponds to your controller-1. If it works, we can look at either adding it to the default cmdline, or add support for specifying either this value or something more flexible.

Cheers,
Don.

Hi,

after setting the personality of our controller-1 we get the follwoing kernel panic:

I suspect that the root cause is the error "nvme nvme0: missing or invalid SUBNQN field."

nvme0n1 is our boot_device and rootfs_device.

Asking Google I'll found something similar (https://unix.stackexchange.com/questions/470778/nvme-missing-or-invalid-subnqn-field). 

What is the official way to change the kernel boot parameters for pxe boot?

Thanks

Marcel
