Please post complete output of devinfo = -r > and pciconf -lvcb somewhere. Sure. Thanks. I created: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237063 and added the two files with the output as attachments. Note: I'm not going to have more access to the system for a few(?) days. Hopefully the 2 files are sufficient evidence for now. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
