I'm using 3.0.35 (stuck >on this kernel version due to other drivers). Do you mean out-of-tree drivers? If they were in the mainline you should be able to upgrade. Anyway, you should at least try to use compat (now called backport) to get the latest wireless stuff. > The good news is that >the chip is detected and wl12xx/wl12xx_sdio loads.

There's nothing very useful in those kids It just shows that the scan command was issued but you never got the scan complete interrupt. -- Luca. -- 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
