[dpdk-ci] UNH CI failing

[Thomas Monjalon]

It seems the IOL CI is failing today:

https://patches.dpdk.org/project/dpdk/patch/1621406749-15536-1-git-send-email-changpeng.liu@intel.com/
https://patches.dpdk.org/project/dpdk/patch/20210519032745.707639-1-stevex.yang@intel.com/

That's especially embarassing for closing the release.

I don't see any useful logs in the failures.

What changed?

As far as I can tell, it looks like one of the clocks fell out of sync on
the container runners, which caused the builds to fail.

Also, as far I can tell from an initial look, it impacted the two patches
Thomas cited.  Two patches that are running now (i.e. they don't have a
full set of results yet, look like they are running on.  So, it was a
transient issue.  Obviously we need to track down its root cause. I suspect
something happened with NTP, which should be keeping the runners and bare
metal systems synced.  I'm looking into that now.

For the patches with the failed jobs, we will queue those for rerun today.

Cheers,
Lincoln

I think that's also been causing some failures with the alarm_test and
cycles_test unit tests.  If the time source is making adjustments to
time, we will probably fail these tests as well.

I'm continuing to hunt. I did confirm all of those systems are syncing time
from the same master, using chronyd, and look to be configured correctly.
I'm not sure what would cause the time to jump like that, unless maybe the
"master", which is our IPA server, synced it's time and that caused some
sort of ripple to the downstream other systems.

The patches have been rerun, with most results coming in,
https://lab.dpdk.org/results/dashboard/patchsets/17130/, and are passing
without issue.

The only failures I see in recent patches are on "bugfix for Kunpeng SVE
compile" (https://lab.dpdk.org/results/dashboard/patchsets/17135/), with
unit tests failing on two OSes.

And the intermittent Dynamic Config failure.  We think we have tracked this
down to a patch we sent into DTS, and that was merged into DTS, but was
then reverted a few days ago (
https://git.dpdk.org/tools/dts/commit/?id=90f460df240b3020191916b15705abe208a14694).
I've asked Lijuan why it was reverted.

Cheers,
Lincoln
