Unfortunately I am on a production machine and due to the server hanging and becoming unresponsive, I had to reinstall ubuntu 12.10 server edition. The problem does not appear in this 12.10
But then I found that this softlockup problem has been solved and the last working kernel version that was reported to be working fine was 3.12.0-8 see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1269404 Now http://www.spinics.net/lists/kernel/msg1716965.html This is a patch that was believed to be solution to the problem. But in the upstream kernels I do not see the patch applied. So could this patch be applied upstream into 3.16 ? Please let me know.
