jffs2 garbage collector crash

[Marc Neiger]

Hi,

I have a Au1000 based board, with JFFS2 on NAND, and the root file system is
in NAND.

An application program is launched by initd and accesses the filesystem.
If I run a few ls from the shell right after booting I get the following
error which I do not understand.
Is it rather some driver problem or an error building the jffs2 filesystem ?
I use the mtd code from 2003.07.03
The system seems not to take some real offense from the crash but I'd like
to solve it !
