I'm having  a hard time getting my DOC to cooperate with the mtd stuff.

I have a MediaGX-based system with a DOC socket on board. I'm using a 16M DOC 
Millenium. Linux is installed on an IDE HDD (hdc).

The DOCs I have were formatted and partitioned with the M-Systems DOS tools. 
They already contain two Ext2 partitions (not sure what created them, but I'm 
guessing it was the old M-Sys Linux stuff.

So... I have the Linux 2.4.5 kernel with the mtd-snapshot-20010619 patched 
in. I built it a few times, sometimes with MTD as modules and sometimes 
compiling the mtd stuff into the kernel. Both seem to do the same thing. In 
the case below, I used the DOC 2000 + Millenium driver.

The problem:
When the DOC on the board is already partitioned, etc., The docprobe detects 
it, as is evidenced by the feedback to the console, the /proc/mtd entry, and 
the fact that I can mount nftla1 and nftla2 and see the contents of the file 
system.

But I wanted to create a single partition, so I followed the steps in the 
jffs howto and did the following:
(0: sometimes do an 'erase')
1: nftl_format /dev/mtd0
2: fdisk /dev/nftla (make one big partition)
3: mke2fs /dev/nftla
4: mount -t ext2 /dev/nftla1 /mnt
5: cd /mnt; touch test

doing an 'ls' on /mnt shows lost+found/ and test. I can umount and remount 
and see the same thing. No errors to the console or syslog, that I have seen.

However, when I reboot, I get the following messages :

After a while, I no longer get any output and there is no 
entry in /proc/mtd.

When I used the Millenium Only driver, I got an error from docprobe saying 
something like "no driver", though I could see it with lsmod.

Attached are:
.config from kernel build (most recent I've succesfully used)
doc_failed_to_find: docprobe did not find the DOC 
log_2.4.5_doc2001mod.txt: no good driver (mod doc2001 was modprobed, though)
log_2.4.5_docprobe: docprobe finds the doc with 2 partitions



Any ideas?

Thanks,

Matt
