Hi Sean,
This is exactly what appeared when I first tried the MTD drivers out on my
system (Virgin webplayer hardware - Geode Gxl 200Mhz SBC). I had to modify
the delay in doc2000.c to be 4 times as long before it would work.
There's a post further back in the list that has a little more detail, and a
small patch that does it is at
http://virgin-linux.sourceforge.net/cgi-bin/ax.cgi?/doc2000-patch
Note that this *really* kills DoC read/write performance.... one day I
might see about adjusting all the delays in there.
Hope this helps,
Dave
