camcontrol rescan all is broken, cannot rescan the buses, 100% reproducible since 11.0-RELEASE (from initial release to p5). Was working on 10.3-STABLE.
# uname -a
FreeBSD bsdrookie.norma.com. 11.0-RELEASE-p5 FreeBSD 11.0-RELEASE-p5 #0 r310364: Wed Dec 21 19:03:58 YEKT 2016 email@example.com.:/usr/obj/usr/src/sys/BSDROOKIE amd64
# camcontrol rescan all
camcontrol: CAMIOCOMMAND ioctl failed: Invalid argument
Kernel and userland are in sync:
# uname -K
# uname -U
It's reproducible even on 11.0-RELEASE Live CD, on different machines.
It seems the problem was fixed in r309943. Is it suitable to make an errata with this change?
