Somebody in the thread at some point said:

| hmm.. I'll need to check this more tomorrow..

Thanks for looking at it... NAND access on stable-tracking is borked
anyway, something about ECC stuff blows CRC errors when you mount jffs2.
~ Did you turn off ECC support?  If not you will likely find a bunch of
junk in dmesg that can explain the slowdown.

Any interest in studying this is mega welcome.
