I have not seen mine boot reliably in a while unless I restrict it to a single cpu core. Also for a long long while I was also using a flat device tree with "set usefdt=3D1". However this is deemed to be fixed :=20 Bug 233863 - Various PowerMac G5 models may require kern.smp.disabled= =3D1 and must set usefdt=3D1 which causes net interface reorder https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233863 Well clearly the net interface re-order is still here.=20 --=20 Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken GreyBeard and suspenders optional --=20 You are receiving this mail because: You are the assignee for the bug.=
