-2 = Z_STREAM_ERROR, meaning the data is corrupt (truncated ?).

Quick workaround:

Compress the kernel instead (make zImage). You don't gain anything
by compressing your image twice.

I saw a similar problem and traced it back to troubles with malloc()
because armboot_real_end wasn't initialized correctly. See my mail:
"Memory layout on PXA" a couple of days ago.

If you are going to use initrd (eg. bootm 0x30000 0x40000) you need
to modify the initrd loading code also (at least I had to...),
since the code doesn't load the initrd to RAM. It passes a
pointer to the image in flash to the kernel instead.
