problem in gunzip kernel!

[Terry B. Chen]

I met problem in gunzip my linux kernel:
The message in serial console is :
January 2000, James Hendricks, Dale Webster, and Ron Minnich.
Version 0.1

203:init_bytes() - zkernel_start:0xfff80000  zkernel_mask:0x0000ffff
Searching for 16 byte tags
    64:rom_read_bytes() - overflowed source buffer. max_block = 7
init_bytes found 0 tags
Gunzip setup
gunzip_setup
output data is 0x00100000
Gunzipping boot code
bad gzip magic numbers

I think we may have error in zkernel_start address or there is a Tag in linux kernel we must do something?

Best Regards
