But that seems to be completly different. Snipped from /var/log/messages:

There was a request to have abrt ignore any part of the stack trace that started with '?' because those are guestimations by the kernel. Before abrt started ignoring those, it would take almost identical stack traces and hash them differently, which was leading to a lot of duplicates.
My guess here is that because _all_ of your stack entries start with '?', abrt didn't work quite as expected.
As for the problem itself, soft lockups inside of virtual guests seem to be somewhat of a norm these days. There is work on-going to get the host and the KVM guest talk to each other in this regard. See bug
