[Bug 1315736] Re: [Dell PowerEdge R720] Machine Check Exception
I seem to have this bug also. While this is on a production server, I have some flexibility in rebooting it. I can note a few issues: 1. The kernel bug only happens with Java (tested both open-jdk7 and oracle8) 2. The java processes block and cannot be killed 3. Any process that tries to inspect the java process becomes blocked (e.g. top, ps, ...). an strace of a ps: open(/proc/41126/status, O_RDONLY)= 6 read(6, Name:\tjava\nState:\tD (disk sleep)..., 1024) = 870 close(6)= 0 open(/proc/41126/cmdline, O_RDONLY) = 6 read(6, [BLOCKS there] 4. As long as no queries are done on the blocked java processes, everything works (though the load of the machine is apparently high) Tell me what you need done to test this, and I will do it -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315736 Title: [Dell PowerEdge R720] Machine Check Exception To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1315736] Re: [Dell PowerEdge R720] Machine Check Exception
Hi Cristopher, The server is a fully installed production server, so unfortunately downgrading to 12.04 is not possible. Reproducing the problem takes about 2 days during which time server is offline. Having the server offline is somewhat problematic. However it is possible to test 3.15-rc5, but I would rather do it in case there is a fix which addresses similar symptoms than reported here. Does the rc5 have a fix which could remedy the problem? Do the provided error messages give any information what might be wrong or is it that they are not helping in this case? I can see that there are some source code line numbers etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315736 Title: [Dell PowerEdge R720] Machine Check Exception To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sami Pietila, could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc5-utopic/ and advise to the results? If reproducible, for regression testing purposes, could you please test for this in the server release of http://old- releases.ubuntu.com/releases/12.04.0/ and advise to the results? ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315736 Title: [Dell PowerEdge R720] Machine Check Exception To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
