Complete console log
starting another run with the non-debug -54 kernel. If possible we need to get a crash dump when this happens. Evidently there is corruption in the slabcache because we are crashing in free_block() while dereferencing a kmem_list. Larry I'll try with the debug kernel again and hopefully get a crash dump this time. By the way, the run I started on Monday with the non-debug kernel is nearly finished. It should finish tonight/early tomorrow morning. So far I haven't seen any issues. I'm running into some issues getting a crash dump out of the debug kernel that looks like bz 612244, so it may be hard to get a crash dump unless I can find a workaround. I've sent mail to Jason B to follow up. This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. If you would like it considered as an exception in the current release, please ask your support representative. This request was erroneously denied for the current release of Red Hat Enterprise Linux. The error has been fixed and this request has been re-proposed for the current release. Does this problem still happen in the latest 6.1 kernel? We removed some buggy debug code from the slab debug code that looks like it was in this area. Either way, I can not reproduce this problem and we never got a dump so I cant make any progress on this BZ until we can get more data. Larry I don't recall ever hitting this on any recent RHEL 6.0 kernel. I think it only occured one time. We have not yet done a longevity test run with any of the 6.1 kernels yet, usually we wait till close to the end of the testing phase, but in light of this bug we'll run it a bit earlier.

This request was erroneously denied for the current release of Red Hat Enterprise Linux. The error has been fixed and this request has been re-proposed for the current release. Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. I've run the longevity test on x86_64 with the beta kernel and it finished without issues. Also ran on s/390x and observed one panic (filed as a separate bz) that had to do with NFS, so I think this one can be closed. |
