Yeah, I've also hit it today, half an hour ago :((

YAFFS1 FS, Linux running off it. No ramdisks, nothing. I can't change
password, passwd gives me "Directory not empty" error. The same error's
given when trying to edit it with BusyBox's vi. Upon bootup mount can not
rewrite /etc/mtab complaining that directory is not empty. What's common to
all those programs is they are all setuid root (vi is a link to setuid
BusyBox). Non-setuid joe works on password file like a charm, no problems
whatsoever. BTW, vi tells me that it wasn't able to rewrite /etc/passwd so
it saved a changed one in a new file, /etc/passwd.edited. Sure enough there
is no such file in /etc...

I don't know what's wrong, it might be just me -- I made an FS image with
mkyaffsimage and put it to NAND with "mkyaffs -e". They both might be buggy
having reached an antique status for being long abandoned so I can't tell
affirmatively that it's YAFFS itself at fault. It's already too late here so
I'm done for today, will try to debug it further on Monday.

And if I hadn't just brutally disabled ALL the YAFFS error messages, I'd
have to get much bigger NAND to store that flood of "**>>ecc error unfixed"
messages in syslog :(( The funniest thing is that /proc/yaffs is shining
with all zeroes in error fields (NAND ECC used)...

Kernel 2.6.12, AT91RM9200 ARM9, yesterdays MTD snapshot, latest (2 month
old, heh?) YAFFS2.
