Azure image used was freebsd-14_2 (14_2-release-amd64-gen2-zfs) published by thefreebsdfoundation. When I tried to change the MTU, the command froze forever: root@echenfreebsd:~ # ifconfig hn0 mtu 1520 up ^C^C^C^C^C^C^C Any further ifconfig calls would also freeze forever when attempting to pri= nt out hn0's information. This is the output of the channel sysctl after the freeze: # sysctl dev.hn.1.channel.12.br.tx.state dev.hn.1.channel.12.br.tx.state: intrcnt:39 rindex:3000 windex:3064 imask:1 psndsz:0 fvalue:1 ravail:64 wavail:520128 --=20 You are receiving this mail because: You are the assignee for the bug.=
