--- Comment #1 from Eric Sandeen <sandeen@redhat.com> ---
First of all, this looks like a rebuilt centos kernel based on RHEL7.0 - i.e a
modified, old, distro kernel.  So upstream bugzilla may not be the best place
for it.

That said, this is down a do_coredump() path, hitting BUG_ON(irqs_disabled())

We've seen similar things on xfs, also down the do_coredump() path, in an
upstream 3.14 kernel (http://oss.sgi.com/archives/xfs/2014-02/msg00325.html).

That launched a long thread, and nobody seemed to come to an answer of why
interrupts were disabled at that point.
