I've got to the bottom of the issue with mSD on the BeagleBone. Basically the GPIO_OMAP option has changed [1] in the 4.2 cycle and this is used for card detection of the mSD card. Prior to this we didn't have it explicitly in our config [2] so it was being selected by something else and it was being built in rather than modular as only with 4.2 can it now be built as modular, and as a result it came up on our radar and was enabled as a module [3]. If I explicitly put this in the initrd it works fine, we have the omap_hsmmc modular too, but it's not pulled in automatically as there's no module dependy by omap_hsmmc on gpio_omap. In the short term I've built it back into the kernel [4] as that's the way it's been for likely ever so it'll appear in the next kernel build after rc8.git0.1 If you want to use any of the other 4.2 kernels you can regenerate the initrd withe the following line in the /etc/dracut.conf file add_drivers+="gpio_omap" Peter [1] http://cateee.net/lkddb/web-lkddb/GPIO_OMAP.html [2] http://pkgs.fedoraproject.org/cgit/kernel.git/tree/config-armv7?h=f22 [3] http://pkgs.fedoraproject.org/cgit/kernel.git/commit/?id=35eff41288ccf2a1ddd555db0b0e51906af970a0 [4] http://pkgs.fedoraproject.org/cgit/kernel.git/commit/?id=5969c87ac95b4f85a579f2cc821900b5aa8b569b _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
