@Jeremy, Could the problem be BIOS related? we have seen a number of
issues with older bioses on the x220s.
Here are a few cards I tested with the 3.1 RC4 kernel on Ubuntu running on
a Lenovo X220. with Ricoh e823 card reader.

This is the upstream RC4 kernel build for ubuntu.

OK, will do.
Thank you!
I don't think we have other reports of this bug, and the
only other person who has reported something like it wasn't a kernel
hacker.
That's interesting; the X220 is a pretty common machine these days, I
think. I wonder if there's variations in the SD controller or something?
I just asked Matthew Garrett to check his X220, and his has the same e823
controller as you, is running a 3.1-rc kernel, and everything's working.
So it's not even variation in the controller model, it's something even
more subtle. Perhaps try some different cards? What capacity/speed is
the one you're trying? If there is a per-card difference, I suppose
we'd expect it to be that slower cards work and faster cards fail
(given the nature of the patch I linked in my last mail).
Thanks,
- Chris.
