And this does not happen if you don't bring wlan0 up? You do have three interfaces all using the same logical network it seems, which makes me wonder where packets go in first place (default route?) and certainly without lagg doesn't seem to make much sense for re0 and re1. You may also want to look into getting (headless) crashdumps setup which may help you to get more information as to what is going on. Are you also using drm-kmod and X? > Here's my ifconfig before the lockup: > > re0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 > mtu 1500 > options=60251b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,LRO,WOL_MAGIC,RXCSUM_IPV6,TXCSUM_IPV6> > ether ??:??:??:??:??:?? > inet 192.168.1.5 netmask 0xffffff00 broadcast 192.168.1.255 > media: Ethernet autoselect (1000baseT <full-duplex>) > status: active > nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> > re1: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 > mtu 1500 > options=60251b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,LRO,WOL_MAGIC,RXCSUM_IPV6,TXCSUM_IPV6> > ether ??:??:??:??:??:?? > inet 192.168.1.55 netmask 0xffffff00 broadcast 192.168.1.255 > media: Ethernet autoselect (2500Base-T <full-duplex>) > status: active > nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> > lo0: flags=1008049<UP,LOOPBACK,RUNNING,MULTICAST,LOWER_UP> metric 0 mtu 16384 > options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> > inet 127.0.0.1 netmask 0xff000000 > inet6 ::1 prefixlen 128 > inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 > groups: lo > nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> > wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > options=0 > ether ??:??:??:??:??:?? > inet 192.168.1.72 netmask 0xffffff00 broadcast 192.168.1.255 > groups: wlan > ssid channel 11 (2462 MHz 11g) bssid ??:??:??:??:??:?? > regdomain FCC country US authmode WPA2/802.11i privacy ON > deftxkey UNDEF AES-CCM 2:128-bit txpower 30 bmiss 7 scanvalid 60 > protmode CTS wme roaming MANUAL > parent interface: rtw880 > media: IEEE 802.11 Wireless Ethernet OFDM/48Mbps mode 11g > status: associated > nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> > > > On 6/12/24 10:44, Bjoern A.
