I had faced similar issue with AU1100 based boards which also use the
zImage patch. It turned out to be board initialization issue rather that
a zImage problem, since after uncompressing the image control is
transferred to kernel_entry.

Subject: "Uncompressing Linux at load address"
I am trying to boot a zImage from micromonitor on a csb655 board
For that matter, I patched my kernel 2.6.15 with the zImage_2_6_10.patch
In the arch/mips/boot/compressed/au1xxx/Makefile, I have set:
1) RAM_RUN_ADDR=0xa0300000, which is the value got from the
APPRAMBASE environment variable.
3) LOADADDR =0x80100000, which is the same value I have set in
entry for this board in arch/mips/Makefile.
I can compile and link the zImage with home build gcc cross tools, based
gcc-3.4.4 and glibc-2.3.4 . When the (binary) zImage is decompressed on
target, I get these messages:
zImage: size=680372 base=0xa0300000
loaded at: A0300000 A03A4000
zimage at: A0306180 A03A3EE1
Uncompressing Linux at load address 80100000
and then the target resets.
This zImage is very small, so the decompressed image is not going beyond
AVAIL_RAM limits. Would you have any guess on what is going on?
I have looked for this information the list through, but anyone seems to
had this problem before. Thanks for any comment.
