Same here. I compiled 3 kernels with each option with no problem, but
none goes beyond the "Uncompressing Linux.." message. I am using a CALAO
USB-A9263 board with the AT91SAM9263 chip.

This means that even zlib compression is broken with this patch.

I hope I can work on this too.

Thanks anyway!

Cheers,

Michael.
