Hi,
With the latest trunk, building madwifi and ebtables packages together throws a kernel panic while brining up ath0 interface
on the Pronghorn IXP4xx board.
Can anybody precise me the source of the kernel panic.?

Kernel panic - not syncing: Fatal exception in interrupt
Rebooting in 3 seconds..+No devices on IDE controller 0
Whereas the interface ath0 works fine when deselecting the ebtables packages.
any ideas pls ?
