Thanks a lot for all the details.
I am using MALTA board with 74K.
From your email I understand that the bootloader must uncompress the
Kernel before launching it, so the compressed Kernel cannot run and
decompress itself? Could you confirm? I am asking that because in some
book I have read that Linux can boot a compressed image and the Kernel
was able to uncompress itself, but maybe it was my misunderstanding.

The answer maybe yes for we have added the basic compressed kernel
support from 2.6.33:
but which board are you using? I just checked the arch/mips/Kconfig of
2.6.35 and only found the following boards enabled it:
bool "Alchemy processor based machines"
bool "Texas Instruments AR7"
bool "Loongson family of machines"
bool "MIPS Malta board"

If your board are not related to any of the ones above, then, you may
need to select SYS_SUPPORTS_ZBOOT for your board and try it.
If it doesn't work, you may need to debug it with serial port or the
other methods. If your board have a 16550 compatible serial port, you
may be possible to select SYS_SUPPORTS_ZBOOT_UART16550 instead of
SYS_SUPPORTS_ZBOOT to enable the serial port debugging support, and at
last, to enable the serial port debugging output, you need to enable
You can get more help from arch/mips/boot/compressed/
BTW, to enable the zboot support, the bootloader of your board may
need the capability to parse the elf file.
