I just built 2.6.27.9-rc1 and disconnected the Windowz box several times. For now smbd does not seem to go into a death spin any more, even though as far as I can tell .9-rc1 does not contain Manfred'd latest patch. Not sure what that means, if anything. I'll keep running stable.9-rc1 and see what happens.. thanks all Holger -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
