hello,
im using 6_stable on sparc64 and get a 100% reproduceable kernel panic.
it crashes when i try to usr/create the tap0 interface. (i discovered it
when i tried to run openvpn).
so i guess it may be the tap driver on sparc64.
i can provice kernel core and offer my help.
i wrote to the sparc64 mailinglist before but now i guess its better off
here.
regards,
Michael Ortmann
