Errors with M-Systems' DOC v MD2200 D16 and ext2

[Mendel Mobach]

Hello

I've got 2 systems with M-systems' DOC
1 with the MD2800 (linux says using the milenium driver) 
(8MD, 1 chip)
and 1 with the MD2200 (16 MB, 2 chips of 8 for mtd0)

With the 2800 I've got no problems but with the 
2200 I've got problems and get some very strange kernel messages

I'm running kernel 2.4.2-pre2 on this system and I attached a harddisk
for development

See below for the kernel and boot messages what kind of problems I've
got

so this is a HELP request from a (l?)user who don't know how to
handle it but wants some help from a expert or someone who knows this
problem
and how I can solve it.

Regards

Mendel Mobach
