Hello, our company built an embedded board which is based on the ARM Freescale imx35 chip. Now I am trying to run a silex sdio wlan module with this board. The Silex module is based on an atheros ar6003 chip. The driver in /drivers/mmc/host/sdhci-esdhc-imx.c (config MMC_SDHCI_ESDHC_IMX) is used for the imx35 processor. When I load the module ath6kl_sdio.ko, I get the following error: "mmc0: Timeout waiting for hardware interrupt". Normal sdcards are working properly. The same timout error appears also with another sdio wlan module which is based on a marvell chip. Thats the reason why I don`t think that it`s an issue of the atheros driver. I think it is an issue of the sdhci-esdhc-imx driver. I searched in the web for a solution to fix it, but I had no success. I hope someone can give me hint, what I can do to get sdio cards working. I enabled the logging for mmc and the following lines are the kernel messages. sdhci [sdhci_data_irq()]: mmc0: DMA base 0x87089e00, transferred 0x076200 bytes, next 0x87100000 sdhci [sdhci_irq()]: ***
