The patch <a href="http://review.whamcloud.com/5665" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/5665</a> was landed on the 12th.</p> <p>I think this must be due to the NRS framework follow-up patch itself, as the version that fired those bugs had some important parts missing. I have just updated that patch and this new version should address this ticket.</p> <p>Thanks Nikitas! As it seems that you are not around to do so (I appreciate it is late on a Friday in the UK) Bob is going to rebase this patch to avoid the <a href="https://jira.whamcloud.com/browse/LU-2910" title="racer test_1, sanity test_54c: ASSERTION( cio-&gt;cui_tot_nrsegs &gt;= cio-&gt;cui_nrsegs ) failed" class="issue-link" data-issue-key="LU-2910"><del>LU-2910</del></a> failure in the hope that we can get a clean test run over the weekend</p> <p>Hi Peter, please proceed to rebase the patch if you want to get a clean test run, though I was planning to refresh the patch at end of day today (so in 5-7 hours from now) after I included some additional changes.</p> <p>Nikitas</p> <p>Ah great - that timeframe works fine to get testing completed over the weekend. Obviously we want the version with the latest changes. I guess that I underestimated the end of your work day <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/wink.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>Peter</p> <p>Xyratex has patch for this issue, probably, I will submit it to master in a few days.</p> <p>ok so the extra tidy up from <a href="https://jira.whamcloud.com/browse/LU-298" title="autoconf dpkg test needs improvment" class="issue-link" data-issue-key="LU-298"><del>LU-298</del></a> that Nikitas believes should resolve this issue has now landed so I am closing this ticket. We can reopen it if there are still problems with this change in place.</p> Related LU-398 Development Rank 1|hzvll3: Rank (Obsolete) 7264 Severity
