S3C6410 SDHCI driver crash

I'm currently experiencing an SDHCI bug in 2.6.31 and linux-next, which 
seem to appear in 2.6.31-rc8.

This is on a new S3C6410 platform (SmartQ 7, see [1]) and it seems to be
consistently happening right after displaying "Loading hardware drivers" (in
user-space; Ubuntu-based).

The relevant kernel log lines are:

blk: request botched
kernel BUG at drivers/mmc/host/sdhci.c:298!

This is on 2.6.31-next-20090923, but I've also had this on regular 
2.6.31, Ben
Dooks latest tree and linux-next with the ADMA patches applied.

Any ideas?
