Description

Motivation

Under the assumption that bsc#1096401 is actually a symptom of other random failures in random test modules we should detect the bug presence, record a soft failure and apply a workaround, e.g. disable snapper

Acceptance criteria

  • AC1: soft_failure to bug is raised when detected

The patch has reached openSUSE Tumbleweed but at least some tests still fail:

[27 Jul 2018 09:43:40] <DimStar> okurz: so, https://openqa.opensuse.org/tests/714806 still fails VLC (still that lxde, which is fine on DVD; will be a fun one) - and the journal no longer shows coredump generation for snapperd
[27 Jul 2018 10:12:15] <okurz> DimStar: thx for letting me know. This is what I expected that snapper core dumping during its shutdown is not really the issue but we ruled it out, that's a start :)
[27 Jul 2018 10:12:58] <DimStar> okurz: well, we did expect it to spoil disk i/o in some scenaios, so having that noise in the logs gone is definitively a good thing
[27 Jul 2018 10:13:42] <okurz> DimStar: sure. I also did not rule out any further I/O causing tests to fail but the LVC looks more reproducible with exactly the same screen
[27 Jul 2018 10:14:30] <DimStar> okurz: VLC now only failed in one scenario at least (the lxde/NET)

With the patch in the product we do not need a workaround anymore and can continue in #38834 to verify it can not happen again unless we just accept it as good enough :)
