https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D269405 Bug ID: 269405 Summary: Problems in PXE booting for laptops with usb ethernet adapter Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: maggiebol89@gmail.com Created attachment 239990 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D239990&action= =3Dedit booting screen photo Hi We need to automate network installation on some laptops.=20 For laptops with Ethernet cards pxe booting works fine in our configurat= ion environment. But for laptops with ethernet Type-C connector (USB), we met s= ome problems.=20 After loading kernel from server, OS starts initializing all devices, but the process of booting stops when system try to mount nfs root file system = (see attached image). It stops with error: nfs_diskless: no interface In nfs_diskless.c we just insert a printf() line to display interface, to make sure about device initialization works properly. retry: CURVNET_SET(TD_TO_VNET(curthread)); IFNET_RLOCK(); CK_STAILQ_FOREACH(ifp, &V_ifnet, if_link) { printf("name=3D%s\n", ifp->if_xname); /* smalll debug */ CK_STAILQ_FOREACH(ifa, &ifp->if_addrhead, ifa_link) { if (ifa->ifa_addr->sa_family =3D=3D AF_LINK) { sdl =3D (struct sockaddr_dl *)ifa->ifa_addr; if ((sdl->sdl_type =3D=3D ourdl.sdl_type) && (sdl->sdl_alen =3D=3D ourdl.sdl_alen) && !bcmp(LLADDR(sdl), LLADDR(&ourdl), sdl->sdl_alen)) { IFNET_RUNLOCK(); CURVNET_RESTORE(); goto match_done; } } } } The result of booting process in attached image. Looks like initialization of usb (also network) happens after system try = to mount root, so we cannot boot system properly. Is that so? Is there any opportunity to boot laptops with USB ethernet adapter via network? May be some workaround. --=20 You are receiving this mail because: You are the assignee for the bug.=
