I assume this is an iso build problem.

Comment 1 Brian Lane 2019-03-18 16:17:39 UTC
I'm not sure what's going on here. f29-branch hasn't changed since 2/28 and the root argument is still set to an empty string (unlike f30 and rawhide).
This error usually means the iso label doesn't match the root line, but on ppc64 we don't set it explicitly so grub2 is supposed to figure it out.

Both of these builds are using the same lorax version according to pylorax.log: version is 29.26-1

So whatever changed wasn't lorax. Moving it to grub2 since that's the bootloader used on the ppc64le iso.

Comment 2 Peter Jones 2019-03-18 17:23:06 UTC
Can you show us what the kernel command line options were in the bootloader?

Comment 3 Michel Normand 2019-03-18 17:50:43 UTC
I apologize for your investigation time :(
As you pointed out the failure was caused by a bad command line option passed to bootloader.
This was caused by an openQA script I locally modified that removed the boot option.

I am closing this bug as user error (worksforme)

Sorry again.
