That " [mi] EQ overflowing" message is completely meaningless. Please, read
http://marc.info/?l=fedora-devel-list&m=124101535025331&w=2 and then take a
look at the disaster which happens when people start to file this message as a
bug at https://bugzilla.redhat.com/show_bug.cgi?id=465884. 

Much more interesting is this backtrace:

Looks like a crash in libdrm (or maybe nouveau driver) to me.
