 The problem is a lot more serious than I first reported. Over the
 last few weeks I've found it pretty easy to panic the system. I
 did more surfing and found this freebsd-hackers thread:
 
     http://groups.google.com/group/mailing.freebsd.hackers/browse_frm/thread/883da63a8c62854d
 
 Ultimately, Doug Ambrisko posts a patch against RELENG_6. I wasn't
 able to recover the patch from his posting but he also committed
 the changes which are available via the cvs web interface:
 
     http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/rp/rp.c?rev=1.67.2.2&content-type=text/plain
     http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/rp/rp_isa.c?rev=1.7.2.1&content-type=text/plain
     http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/rp/rp_pci.c?rev=1.11.2.2&content-type=text/plain
     http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/rp/rpreg.h?rev=1.7.2.1&content-type=text/plain
     http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/rp/rpvar.h?rev=1.8.2.1&content-type=text/plain
 
 It looks good! I've been unable to generate a device_unbusy() panic
 with the resulting kernel.
