Hi, I was trying to troubleshoot DHCP failing on a fresh Haiku installation, when I accidentally added a network interface. There is already /dev/net/pcnet/0, and I ran
ifconfig /dev/net/pcnet down; ifconfig /dev/net/pcnet up in an attempt to jolt the device into acquiring a DHCP lease.
Instead of down’ing the preexisting /dev/net/pcnet/0 device, this resulted in the creation of a new listing, /dev/net/pcnet, in ifconfig. Then, when I tried to remove this additional listing with
ifconfig --delete /dev/net/pcnet, I triggered a kernel panic.
