S= ee: https://bugzilla.yoctoproject.org/show_bug.cgi?id=3D15647 It seems that the problematic commit is: a180e82837 Linux: Make __rseq_size useful for feature detection (bug=20 31965) but let's get that confirmed in the bug report. The lesson learned is that if there's a regression from a glibc update=20 even a single intermittent failure, we should spend more time investigating the problem. Deepthi did re-run the tests both manually and as part of the test suite=20 only to find that the issue was not reproducible but in hindsight, we could have done more. We'll work on improving our testing. ../Randy > >> Please find the following results after the update which has 2 less fa= ilures than the results before update. >> After Update >> PASS - 4781 >> FAIL - 145 >> XPASS - 6 >> XFAIL - 16 >> UNSUPPORTED - 237 >> >> Before update: >> PASS - 4770 >> FAIL - 148 >> XPASS - 6 >> XFAIL - 16 >> UNSUPPORTED - 237 >> >> Diff: >> PASS - +11 >> FAIL - -3 >> XPASS - 0 >> XFAIL - 0 >> UNSUPPORTED - 0 >> >> >> >> >> -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D- >> Links: You receive all messages sent to this group. >> View/Reply Online (#205207):https://lists.openembedded.org/g/openembed= ded-core/message/205207 >> Mute This Topic:https://lists.openembedded.org/mt/108647219/3616765 >> Group Owner:openembedded-core+owner@lists.openembedded.org >> Unsubscribe:https://lists.openembedded.org/g/openembedded-core/unsub [= randy.macleod@windriver.com] >> -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D- >> --=20 # Randy MacLeod # Wind River Linux --------------mRShFpuBvO27PdbSRyt1XAA9 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable X-MIME-Autoconverted: from 8bit to quoted-printable by mx0a-0064b401.pphosted.com id 4AE6o079030582

Hi Khem & Steve,

Thanks for checking out the results and your comments.


Is this regression? an=
d is it a persistent failure?

We analyzed the issue furt=
her by debugging it manually and observed that the testcase "nptl/ts=
t-thread-affinity-sched.c" passed as expected. Hence, we ran the tes=
tsuite again after the update and found that the issue was not reproduced=
 anymore.

Thanks, I wonder why it fail=
ed the first time. Was the system running
these suites overloaded ?, I would like to see if there is a pattern
to these failures.
for now this looks ok to me to apply.

Interestingly (in a bad way!),
this regression may be related to a problem that Stephan just reported. See:

   https://bugzilla.yoctopr= oject.org/show_bug.cgi?id=3D15647

It seems that the problematic commit is: 
a180e82837 Linux: Make __r= seq_size useful for feature detection (bug 31965) but let's get that confirmed in the bug report.


The lesson learned is that if there's a regression from a glibc update even a single intermittent failure,
we should spend more time investigating the problem.

Deepthi did re-run the tests both manually and as part of the test suite only to find that the issue
was not reproducible but in hindsight, we could have done more.

We'll work on improving our testing.
