Being new, I did not have dumpdev set in rc.c= onf, and my root device is ZFS, which I snapshot before the upgrade and I c= ompletely rolled back after rebooting, before looking for any dumps. If I a= ttempt the upgrade again, I have dumpdev configured now, and I will not rol= lback /var/crash after rebooting. >=20 > > At least, look up the source line number for the VOP_ADD_WRITECOUNT_APV= +0x78, > > by loading the kernel.debug into kgdb and doing > > list *VOP_ADD_WRITECOUNT_APV+0x78 > > The lines should be from the build-time generated file vnode_if.c, so p= lease > > provide the excerpt from the source file around the reported line. >=20 > I am running a GENERIC amd64 kernel, which I have not compiled. Is there = a way to deduce the appropriate line without a dump? Or, would I need to tr= igger a panic in another machine running the same kernel? >=20 The system comes with kernel.symbols file, which should be enough.

If yes, did you recompiled them after the upgrade ? >=20 > I do not have any out-of-tree kernel modules installed.

I have no idea what ipl.ko is. I think you should start with recompiling whatever modules you have besides base system, before we go any further. --qlxuSZavbKOzr4aO Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (FreeBSD) iQIcBAEBAgAGBQJSeb1NAAoJEJDCuSvBvK1Bz1wP/3iqIKFMhwBUko96fhQmijPk LtIPYUJECj9rvhFIkzL3C9ayy1nJS6LnFCwSOWFTDMMLIngLeTgPjQCFnZiWs4eH GU6t/IO/5doovuFW0bBXEAUzMY0Pb7bjIzFopvPdRWBzh4kJ3diFg/yjkLhy1rvr 9so2P47tthZ5zwY5PKRPjWF6Fx7lGPVLskcDjcDHThKAW3tJJInNkjwgMX5zDu/f j7oDgHQVG9FmuAa1lrMp/mfP3gWyKX8T7YyN8ey+W1/ha9G8aHkfdyNRk3sGtEYX mQr/QEerCWMwgq6ORVoFxhioNDMw6pwVc2A8l+t+T7ajZs+yHl/DSOKHXNYv4vcF xhDIis6V999iMGB7PYRkVzu6bz8ffhQgZbjyOlliFdfsq5iVFyHH0oEAHlhqTfeW DIeeGjY5pzMKc3DFM5PNnLAEWPaX9Wv36r2+ZOkCH7y9EzLZe6VtzyUd1IFX/OSk T0i1hTxfSB/DA2+rG3UCQ4QzX7vKVgmLcORHc3u4+ztgfoe2u0WmYyEmdQHS3HBt F5df+QRZvg5xDxdjGGtC7R/ouNk1z6izTYgPs/yxxUOHnpXr8UwtldOx5ZZzBGR2 Qi+9/Wwz7dXjHjLpxJl5YYedzTWsh8XwR0VzJo8BRdhZB+3wB5xCR/6jvaUKGWfZ fbDQh9TQbluWKlMCBgTT =D7xf -----END PGP SIGNATURE----- --qlxuSZavbKOzr4aO--
