Description

Observation

System fails to boot after install, it was hard to say if was an infra issue, so we tried on a different environment to see if it happens again, and it did but then passed the next time.

But then it failed again. In one of the runs, I had blocked state boot at "a start job is starting for dev/mapp..." (then it's truncated) and I couldn't ssh there. See attachement.

We need to figure out which update triggers it. There are several updates I have on my highly suspect list (in order of suspicion) :

libmount and others : https://download.suse.de/ibs/SUSE:/Maintenance:/25242/SUSE_Updates_SLE-SERVER_12-SP3-LTSS-TERADATA_x86_64/x86_64/
systemd: https://download.suse.de/ibs/SUSE:/Maintenance:/24472/SUSE_Updates_SLE-SERVER_12-SP3-LTSS-TERADATA_x86_64/
kernel-default: https://download.suse.de/ibs/SUSE:/Maintenance:/25294/SUSE_Updates_SLE-SERVER_12-SP3-LTSS-TERADATA_x86_64/x86_64/
openiscsi: https://download.suse.de/ibs/SUSE:/Maintenance:/25336/SUSE_Updates_SLE-SERVER_12-SP3-LTSS-TERADATA_x86_64/x86_64/

The other updates are very unlikely to provoke this kind of problem.

We need to try running the jobs several times (as it is sporadic) with those updates excluded separately, then report a bug once faulty update is identified.

All fine, thanks for the investigation, I think this test is not suitable to be running in maintenance updates, the more bother us this sporadic issue, the more reasons to move it to development group and investigate why the test suite was created, feature where was required, etc.
