https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242180 Bug ID: 242180 Summary: kern.cam.boot_delay=3D"10000" parameter in /boot/loader.conf stopped working. Catastrophe! Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: michael.adm@gmail.com After applying the 4a46b2449c63e010014dc0fb2a3caa5e20b97933 commit, the kern.cam.boot_delay=3D"10000" parameter in /boot/loader.conf stopped workin= g. Catastrophe! Now I have to load mlx4en.ko in firewall rules! =C2=A0(in /etc/rc.firewall adding at end "kldload mlx4en") The main problem is described here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241639 Please correct the situation. commit 4a46b2449c63e010014dc0fb2a3caa5e20b97933 =C2=A0 =C2=A0committer mav <mav@FreeBSD.org> =C2=A0 =C2=A0 =C2=A0Fri, 22 Nov 2019 20:39:51 +0200 (18:39 +0000) =C2=A0 Make CAM use root_mount_hold_token() to delay boot. Before this change CAM used config_intrhook_establish() for this purpose, but that approach does not allow to delay it again after releasing once. USB stack uses root_mount_hold() to delay boot until bus scan is complete. But once it is, CAM had no time to scan SCSI bus, registered by umass(4), if it already done other scans and called config_intrhook_disestablish(). The new approach makes it work smooth, assuming the USB device is found during the initial bus scan. =C2=A0Devices appearing on USB bus later may s= till require setting kern.cam.boot_delay, but hopefully those are minority.
