Yeah, this is just the symptom though - pm_runtime_get_sync tries to power up the card, and eventually mmc_sdio_init_card() is called (by mmc_sdio_resume which is invoked by mmc_resume_host).
On the XO-1.5 mmc_sdio_init_card() seems to fail due to mmc_send_relative_addr() returning -110; this may suggest that although mmc_power_off() and mmc_power_on() were called, we still didn't have a full power reset, and the card/controller are left at a weird state.
Can you please check out if that's the same failure in your case too ?
Thanks! Ohad.
