[panic] ipw and kismet

[Ulrich Spoerlein]

Hello,

I almost always get a panic when running kismet on my ipw-Interface
under 6.1-PRERELEASE. This has been the case ever since ipw hit the
tree. Sometimes kismet works, sometimes it doesn't. A sure way to
trigger the panic is to switch between bss/ibss/monitor mode prior to
running kismet. Perhaps there is a bug in the re-initialization when
loading a different firmware?

Is this panic known? Does the new firmware-framework address this?

Which is worse: ignorance or apathy?
Don't know. Don't care.
