Issue #2296 has been updated by Thomas Nikolajsen.

Some additional observations:
I have only seens this issue on i386, not on x86_64,
so it seems to be specific for i386.

I have only seen issue while doing buildworld
(e.g. as part of make release), not while doing quickworld.
(this & kernel build is the parallel workloads I do most on this host)
As originally noted: issue seen with -j10 on 8 core system using SMP kernel;
not seen w/o -jN; haven't tried lower N.

On UP system running SMP kernel I haven't observed issue;
this was using -j3.
Bug #2296: panic: assertion "m->wire_count > 0" failed

Author: Thomas Nikolajsen
Status: New
Priority: Normal
Target version: 

With recent (29/1-12) master and rel3_0 I get this panic
during parallel make release and buildworld, e.g.:
'make MAKE_JOBS=10 release' (i.e. make -j10)
(custom kernel, includes INCLUDE_CONFIG_FILE)
on 8 core host (opteron).

Got this panic twice; succeeds w/o MAKE_JOBS
