I'm not yet sure why, but the only response I get is loop of: mmc0: Timeout waiting for hardware interrupt. mmc0: Internal clock never stabilised. mmc0: Timeout waiting for hardware interrupt. mmc0: Internal clock never stabilised. This only happens on the hsmmc channel using the gpio-based card detect and even prevents the card from beeing fully detected. The other hsmmc channel using a permanent emmc seems to be working fine. And of course, when I revert this patch everything works fine again. I'll investigate further, but it'd be also ok if someone has a fix for this before me :-) . Heiko
