That said, I'm using wireless-testing with a patch for the scanning state machine (hopefully it will be committed today). The output of dmesg doesn't show anything interesting. The stack dump from the video card is unlikely to be related. But I think you may be getting something when the freeze happen. But to see it, you need to be on a text console. There are other ways to capture the kernel messages, which are described in the file Documentation/oops-tracing.txt in the Linux sources. -- Regards, Pavel Roskin -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
