Subject: Bio device too big | kernel BUG at mm/filemap.c:537!

I booted up the new kernel version, 2.6.20; I pretty much copied over my
.config that worked in 2.6.19.2, that has worked correctly since that
version came out... I looked through the menuconfig to see if any new
options had been added, but I'm pretty sure I didn't change anything,
and got this error message shortly after booting:

The devices it seems to be complaining about are /dev/hdg and /dev/hde,
which are physically attached to the PCI0680 Ultra ATA-133 Host
Controller listed in lspci.txt.
Both drives are 160 GB Western Digital HDDs... don't remember the
precise model, but I can find out if necessary.

Attached are the output of lspci and my .config; if anyone needs further
info, let me know.
