Hi Wolfgang,

I did exactly that, I took rc1, downloaded the zlib-1.2.3 patch from the
newsgroup[1] and added the patch by Alessandro[2]. The WATCHDOG_RESET code
in gunzip.c is not touched by either patches, but I still get a
WATCHDOG_RESET when the kernel image is decompressed with the new code.

Though is seems that

if (z->outcb != Z_NULL)
     (*z->outcb)(Z_NULL, 0);

is not used anymore in zlib.c so the WATCHDOG_RESET calls are silently
ignored. I will try to re-add them tomorrow.

Besides this, rc1 is working fine here.

Cheers, rhabarber1848
