jffs2: inflate returned -5

[Alexander Stein]

Hello,

I recently got a kernel panic during boot while accessing a JFFS2 filesystem 
on NOR flash. There was an error message as stated in the topic ' inflate 
returned -5'. The board is using an AT91SAM9G20.
I checked the source and this seems to be fs/jffs2/comp_zlib.c:180. But what 
I'm wondering about is that zlib_inflate is called with flush = Z_FINISH which 
means that not enough room for data or no progress is possible, according to 
the zlib headers.
In which cases can this occur? I think there should be enough memory available 
(32MB attached).

Here is the full kernel log:
