https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225794 Jeremy Chadwick <jdc@koitsu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jdc@koitsu.org --- Comment #4 from Jeremy Chadwick <jdc@koitsu.org> --- freebsd-stable mailing list also has this, indicating an MFC has now caused this problem in -STABLE: https://lists.freebsd.org/pipermail/freebsd-stable/2018-February/088393.html "VM image for 11.1-STABLE began exhibiting same dislike for USB 3.0 ports as problem reported in PR 225794 for 12.0-CURRENT. Prior to FreeBSD-11.1-STABLE-amd64-20180215-r329320.vmdk.xz no such problem was observed." CAM status 0x44 refers to done_ccb->ccb_h.status per sys/cam/scsi/scsi_da.c, function dadone(). done_ccb is declared as "union ccb *done_ccb". Field c= cb_h is likely declared as "struct ccb_hdr ccb_h" (this is commonplace). Field status is therefore "u_int32_t status" per sys/cam/scsi/cam_ccb.h, which sh= ould correlate with the cam_status enum per sys/cam/scsi/cam.h. I had to write a small program to dump all the enum names and values because the ordering and mid-struct value assignments result in hard-to-read code. Text strings come directly from cam_status_table[] per sys/cam/cam.c, except for QFRZN, which comes from the .h file itself. 0x04 =3D CAM_REQ_CMP_ERR =3D CCB request completed with an error 0x40 =3D CAM_DEV_QFRZN =3D The DEV queue is frozen w/this err Suggest involving avg@, hselasky@, and emaste@ You will probably be asked = to try older commits to try and narrow down what exact commit broke things. stable/11 commits: http://www.freshbsd.org/search?branch=3DRELENG_11&project=3Dfreebsd HEAD commits: http://www.freshbsd.org/?branch=3DHEAD&project=3Dfreebsd --=20 You are receiving this mail because: You are the assignee for the bug.=
