next in thread | raw e-mail | index | archive | help
Hello,
I get a panic each time I try to create an access point
with the ural driver.
only by running this commands the machine panic:
kldload bridge
sysctl net.link.ether.bridge.enable=3D1
net.link.ether.bridge_cfg=3D"rl0,ural0"
I'm not very familiarized with 'kgdb' so if some developper
gets interested in this panic I can execute all commands
they are interested in.
thank you.
