Hi, on todays Linus' git (v2.6.36-9871-g3985c7c) b43 sdio stopped working. It was working on (v2.6.36-6794-g12ba8d1). b43-sdio: probe of mmc0:0001:1 failed with error -16 The error seems to originate from the following code in drivers/mmc/core/sdio_bus.c:sdio_bus_probe() 135 ret = pm_runtime_get_sync(dev); 136 if (ret < 0) 137 goto out; so I suspect this has something to do with the following commit: commit 40bba0c1ca83a370f749c8bc9afda71cf79ebd91 Author: Ohad Ben-Cohen <ohad@xxxxxxxxxx> Date: Sat Oct 2 13:54:11 2010 +0200 mmc: sdio: enable runtime PM for SDIO functions However, simply reverting 40bba0c1ca83a370f749c8bc9afda71cf79ebd91 does not work because then modprobe hangs. Tested on AP4EVB (arm) with tmio_mmc. Any ideas?
