Error: jffs2_decompress returned -5

So,

After patching 2.4.27 with the snapshot from today, and adding "__ffs" to
compatmac.h , everything compiles, but then when reading my jffs2 file
system I get this :

I haven't seen those errors before.   Anyone care to point me in the right
direction?

I think you specified a compression type when building the image with 
mkfs.jffs2, which isn't selected in the kernel config. But I can't tell you 
which type 0x06 is.

0x06 means ZLIB. (you can check it in jffs2.h)

Is there CONFIG_JFFS2_ZLIB in your kernel config?

Ah no, that's not set.  I'll check turn that on and try again Monday.
