 Can you go on IRC (freenode, #olpc) ?  If so, I would like to work with 
 you to see if my latest firmware works around your problem.

I've pushed changes to the OLPC kernel tree which should cope with this
problem, and should prevent it happening again. More to the point, the
code should now tell us _why_ it was happening. I'd very much like it if
someone could run the new kernel, repeat whatever they did to cause this
thing to happen in the first place, and then give me all the kernel
messages following the one which looks like:
'Error in jffs2_write_dirent() -- name contains zero bytes!'

something went wrong in the file system

2007-10-12 Thread Yoshiki Ohshima
  Hello,

  My B4 with 616 build went into some interesting state.  I was
copying some executable files to a directory (under /usr/local/lib/)
from my USB memory and playing with it (for several iteration) from
the Sugar console.  But I terminate the executable and left the system
idle for a night.  That was yesterday.

  Today, I was trying to remove the file I copied by rm command but
get an error that says No space left on device.  I try to reboot my
machine (perhaps a bad idea) but it went into the launching X loop.

  I did force poweroff and now the unit doesn't boot.  I got OFW's
ok prompt and typed:

dir nand:\boot

but it says:

jffs2-file-system
jffs2:bad read

I saw some trac items about nand corruption and it might have happened
to me.  I don't know if there is a way to salvage some useful
information from my unit at this point, but if somebody has an idea
(or just say it is a known problem) please let me know.  Otherwise,
I'd just reinstall a build...
