https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D243223 Bug ID: 243223 Summary: [vtnet] panic during boot when IP is assigned in /etc/rc.conf Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: alfredo.junior@eldorado.org.br While testing a custom kernel with virtio drivers bultin on FreeBSD 13/powerpc64, I hit a panic during boot. I have the following line in /etc/rc.conf: ifconfig_vtnet0=3D"inet 10.10.20.73 netmask 255.255.255.0" If I remove this line, kernel boots correctly. Also NIC works normally if I configure the IP address manually after boot. kernel log during boot: vtnet0: link state changed to UP panic: keg vtnet_tx_hdr initialization after use. cpuid =3D 0 time =3D 1578601768 KDB: stack backtrace: 0xe00000005a459140: at kdb_backtrace+0x60 0xe00000005a459250: at vpanic+0x1d8 0xe00000005a459300: at panic+0x40 0xe00000005a459330: at uma_zone_reserve+0x160 0xe00000005a4593e0: at vtnet_debugnet_init+0xac 0xe00000005a459440: at debugnet_any_ifnet_update+0x74 0xe00000005a4594f0: at dn_ifnet_event+0x28 0xe00000005a459520: at do_link_state_change+0x29c 0xe00000005a4595d0: at taskqueue_run_locked+0x184 0xe00000005a4596a0: at taskqueue_run+0x64 0xe00000005a4596e0: at taskqueue_swi_run+0x28 0xe00000005a459710: at ithread_loop+0x2cc 0xe00000005a459820: at fork_exit+0xc4 0xe00000005a4598c0: at fork_trampoline+0x18 0xe00000005a4598f0: at -0x4 KDB: enter: panic [ thread pid 12 tid 100024 ] Stopped at kdb_enter+0x78: ori r0, r0, 0x0 db> --=20 You are receiving this mail because: You are the assignee for the bug.=
