Grrr. This is not supposed happen. (I tested this here. Grrr, again.)

I must have a look on this. Please send me this ISO in private.

Compressing the ISO again should reduce it further. Most of it is still
32 KiB zeros and quite redundant ISO 9660 directory data. The compressed
data sit in the last 2048 bytes of the ISO.

Own adventures:

So far i found a flaw in the kernel's zisofs code which is about all-zero
blocks and thus does not apply to the given case.
Further i believe to see that every second compressed chunk is not
properly announced by zlib_inflateInit(). But a compelling reason for -EIO
has still to be found.

Whatever, first i need to see what your kernel gets to see. I.e. the ISO.


Have a nice day :)
