I've tested hostapd on ixp425, but have not seen something like this
show up. Then again, I haven't tested it with madwifi driver on ixp425.
This kernel oops looks more like an indication of a bug in the kernel
driver (maybe in ath_hal module) than an issue in hostapd.. Have you
tried using this device as an AP without hostapd (e.g., in plaintext
mode and configure the interface with iwconfig and ifconfig)?
