Issue #2296 has been updated by Thomas Nikolajsen.

Did tests on master (w/o patch), got panic, as expected.

Did 4 'make -j10 buildworld buildkernel' test runs,
had one panic during first run.

Test was same setup as prev. run: 
used MAKEOBJDIRPREFIX on tmpfs this time (and /usr/src on NFS, as usual),
on 8 core system w/ 8GB running i386 (i.e. using ~3GB (4GB minus PCI mem. space)).
Bug #2296: panic: assertion "m->wire_count > 0" failed

Author: Thomas Nikolajsen
Status: In Progress
Priority: High
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
