Yes, on the master branch. I'm using my own config. It was working on
2.6.35 or so. I tried backporting my board patches to 2.6.36 and it
fails there too now for some reason. It might be the SD card, I'll
have to find another one and try it out.

This appears to be caused by commit 4c2ef25f (mmc: fix all hangs
related to mmc/sd card insert/removal during suspend/resume). Enabling
CONFIG_MMC_UNSAFE_RESUME seems to fix it. Ideally, it would be nice to
have the root file-system on a mmc regardless of whether or not it's
removable or not.

Good.

You'll have to take that one up with the MMC core.
I'm sure they would welcome patches to fix it. ;)
