This is pointer to the pipeline:

Qemu is okay here, too.

Qemu is ok.

Qemu is ok.

Qemu is ok.

https://gitlab.com/cip-project/cip-kernel/linux-cip/-/pipelines/266539768

So... failure apparently went away when trying to
bisect. That's.... strange? Aha, except that it looks like the same
"suceeded" tests still have failures in them:

https://lava.ciplatform.org/scheduler/job/173186

[   26.224557] <LAVA_SIGNAL_TESTCASE TEST_CASE_ID=CVE-2017-5715
RESULT=fail>
Received signal: <TESTCASE> TEST_CASE_ID=CVE-2017-5715 RESULT=fail

...I guess those fails are expected, then? And qemu tests on
-stable-rc are really failing on timeouts. ... Hmm, let's just re-run
the tests.

I'm still not sure, but it looks like a test failure now.

Best regards,
