Of course the power is not cut when I remove the mwifiex_sdio module. Under this kernel, I'm not sure if the power is or isn't being cut at this point. I don't think this is relevant though; regular insmod/rmmod cycles work fine, the problem only appears when tearing down the interface while a scan is in progress. > I can upgrade my XO-4 to kernel 3.8 if feasible. Please let me know if a HOW-TO doc is available. You will need a serial console connected, as there is no output on the LCD at this time when running the upstream kernel. http://wiki.laptop.org/go/User:DanielDrake/Run_upstream_kernel_on_XO-4 Daniel -- 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
