OK.
re-did everything from scratch. Dformat doc42.exb and loaded modules
modprobe -a doc2000 nftl mtdchar mtdcore
modprobe -a docprobe
the end of the output is.

Ok.
I formated the disk with dformat and reran the modules
I get this...
[root@ba /root]# modprobe -a doc2000 nftl mtdchar mtdcore
[root@ba /root]# modprobe -a docprobe
DiskOnChip 2000 found at address 0xD0000
Formatting block 2
Formatting block 3
Formatting block 9
Formatting block 11
Formatting block 13
Formatting block 15
Formatting block 17
and it has been sitting here for quite a while now.
the message repeated in log is....
Mar 1 14:36:12 ba kernel: _DoC_WaitReady called for out-of-line wait
Mar 1 14:36:43 ba last message repeated 8365 times
Mar 1 14:37:44 ba last message repeated 17039 times
Mar 1 14:38:45 ba last message repeated 17045 times
...
I apologize, I'm not sure what you mean by logging the serial term..

Hmm. Did you do this from scratch, starting by reformatting the NFTL again?
It doesn't look like it.
Use the M-Systems DFORMAT (version 4.2) if you can, rather than nftl_format.
If you do use nftl_format, make sure the NFTL kernel module isn't loaded
while you do so.
Then get logs again, preferably over a serial console, because syslog is
lossy.
I may have a 288MiB unit here, in fact - I'll see if I can reproduce it
myself.

I shut down syslog, and everything is going out to the terminal now,
however, it just keeps scrolling
_DoC_WaitReady called for out-of-line wait
accross all my tty's, and I can't stop it!
