That's the root cause.  I fixed this with the Freescale i.MX SD driver
which is now able to report pending SDIO interrupts while runtime PM

Other host drivers probably need fixing too, or having runtime PM
disabled on them - if you can't receive SDIO interrupts while runtime
PM suspended, then entering runtime PM while you have a SDIO device
attached is a bug.

This is something for the MMC people to deal with rather than Arend.
