Yeah, I noticed those issues too. I've been looking into properly
implementing resume/suspend according to the SSDHC spec (the driver
right now saves and restores the first 14 bytes like the spec says,
but it doesn't actually issue the resume or suspend commands).

I also noticed that when I broke into the kernel debugger (or maybe
config, I forget) and ejected the SD card, the kernel later hard
locked.
