The following reply was made to PR kern/109152; it has been noted by GNATS. From: Craig Leres <leres@ee.lbl.gov> To: freebsd-gnats-submit@FreeBSD.org Cc: ambrisko@ambrisko.com Subject: Re: kern/109152: [rp] RocketPort panic from device_unbusy() Date: Wed, 07 Mar 2007 20:21:21 -0800 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. Craig
