inflate returned FFFFFFFD - what does this error exactly mean ?

[Povolotsky, Alexander]

Hi,

After few days of wondering through debugging (and with great help) I fixed
(by inserting watch dog resets into beginning of  while loops in zlib
functions) my first problem -strange reboot failures during decompression of
the kernel image by the bootloader.
However my luck expired beyond this fix so far ... ;-).
Now I am getting "controlled" failure (during the same decompression as
described above):

I_BAD
return Z_DATA_ERROR
after zlib_inflate
inflate returned FFFFFFFD
exit

what does this error exactly mean ?

Thanks,
Best Regards,
Alex
