hp-bl460c-02.rhts.eng.bos.redhat.com is marked as broken in beaker now, we can get the vmcore after it is ready.
Unless the vmcore can be provided, it is impossible to debug this backtrace issue.
Please either provide the vmcore or close this BZ. If it can be reproduced, and the vmcore provided, then a new BZ can be opened, or this one can be re-opened.
That machine is still broken... let's close it now.
