I'm not sure if this makes sense, but it looks like the partition was
created with a 16 head scheme, and the kernel is trying to read it with
a 255 head scheme.  Did you move the drive to a different controller
after you partitioned it?  Most modern drives will simulate either
scheme, so it isn't fatal, but it looks like the kernel is missing the
ends of the primary partitions.

Good Luck,
