This is current/amd64 on a Dell Latitude E5570 (dmesg below). When booting without the ethernet cable plugged in, the boot sequence finishes with the following message:
em0: Hardware Initialization Failed em0: Unable to initialize the hardware So, the cable is not it now: $ ifconfig em0 em0: flags=8803<UP,BROADCAST,SIMPLEX,MULTICAST> mtu 1500 lladdr 28:f1:0e:26:94:75 index 2 priority 0 llprio 3 media: Ethernet autoselect (none) status: no carrier The I plug the cable in: $ ifconfig em0 em0: flags=8803<UP,BROADCAST,SIMPLEX,MULTICAST> mtu 1500 lladdr 28:f1:0e:26:94:75 index 2 priority 0 llprio 3 media: Ethernet autoselect (10baseT full-duplex) status: active But it won't get a DHCP lease: $ doas dhclient em0 doas (h...@dell.stare.cz) password: em0: no link ........... sleeping $ doas dhclient em0 doas (h...@dell.stare.cz) password: em0: no link .......... sleeping $ doas dhclient em0 doas (h...@dell.stare.cz) password: em0: no link ........... sleeping When I boot with the cable plugged in, everything works as expected, like it always has. But now it seems that the ethernet cable _must_ be plugged in at boot, otherwise em0 will just not work. Can somebody with em(4) reproduce? How can I debug this?
