Comment 1 Cong Wang 2012-01-20 07:24:16 UTC 
hp-bl460c-02.rhts.eng.bos.redhat.com is marked as broken in beaker now, we can get the vmcore after it is ready.
Comment 5 Dave Anderson 2012-07-10 15:13:43 UTC 
Unless the vmcore can be provided, it is impossible to debug this
backtrace issue.
Comment 6 Dave Anderson 2012-07-10 15:16:29 UTC 
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.
Comment 7 Cong Wang 2012-07-11 01:48:21 UTC 
That machine is still broken... let's close it now.
