Why are you doing that ? I'm using 'cp' over /dev/mtd0 as said in the
mtd-jffs-HOWTO :

cp  /tmp/jffs.image /dev/mtd0,1,2

Actually 'dd' is a more flexible 'cp'. Anyway I tried both ways.

Here's where I was wrong. The mount works but the system freezes for about
30 seconds (YUP) so I thought the system was hung. Anyway, issuing a
"touch /mnt/silly" crashes the system, giving me the same kernel oops. I
increased the debugging level of printk, as you adviced in your previous
post but I cannot post neither the debug messages nor the kernel oops
itself : tomorrow I will buy a NULL modem cable and I'll try to catch the
messages through the serial port.

Taking a look to the stack trace is giving me the impression that my last
backtrace was correct and the reason why this happens is always the same
"invalid operand".
