This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

But Xenial does not have the above patch.

Hi Tim,

Can you please remove this tag 'verification-needed-xenial' for now as the fix is not
yet released for Xenial.

Enable the tag once it is released for Xenial.

commit 8f1d3b68ff08466f55c55e03f9aa4d989c515095 (powerpc/powernv : Drop reference added by kset_find_obj()) was released in UBUNTU: Ubuntu-4.4.0-39.59 which never made it out of proposed. It has since been superseded by Ubuntu-4.4.0-41.61 due to regressions respins. That is the version that you should be verifying.

system is not booting after selecting host from petitboot with Ubuntu-4.4.0-41.61 kernel
and its is not related to this patch even without this patch also it is falling into below case.

Gave up waiting for root device. Common problems:

- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)

Mukesh - you need to get your developers to look at this failure to boot.
