--- Comment From mauri...@br.ibm.com 2017-12-11 11:08 EDT--- Hi Joseph, > @Mauricio, I was just wondering if there was results from the testing > mentioned in comment #18? Unfortunately that kernel patch alone did not resolve the problem. This bug seems a bit stale, waiting for developer/analysis cycles. cheers, Mauricio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708130 Title: ISST-LTE: Ubuntu16.04.03: PowerNV: 'ppc64_cpu' commands hangs while changing SMT value with Leaf IO and BASE tests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1708130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wendy, reassigning back to you for further analysis, as only Paul's patch was not sufficient to fix this problem on Ubuntu.

--- Comment From mauri...@br.ibm.com 2017-08-22 11:50 EDT--- @Joseph, > @Mauricio, > > Do you plan on submitting an SRU request to the Ubuntu kernel team mailing > list once testing is verified by Indira? Yes, exactly. If you'd recommend to submit it earlier, since already accepted upstream, I can do that -- We know this patch fixes problems with similar symptoms on other distros / duplicates, but since this involves a SRU request to LTS, in an area such as RCU, I'm clearly following the SRU requirement of testing first. :- ) cheers, Mauricio -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708130 Title: ISST-LTE: Ubuntu16.04.03: PowerNV: 'ppc64_cpu' commands hangs while changing SMT value with Leaf IO and BASE tests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1708130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
