I'm upgrading from 2.4.3 to 2.4.17 (rsync from mvista) on a Walnut-variant board. The initrd seems to be getting corrupted. The kernel crashes during the decompress or prints "crc error" or "invalid compressed format" messages. I have allocated enough space by using the 'ramdisk=32000' command line option. The same ramdisk works fine on a 2.4.3 kernel.
I've used my BDI to dump the initrd image back onto my workstation, and gunzip also complains about the file format. So it really is getting corrupted. The beginning of the file looks ok in a hex editor. Also the loader addresses look ok, no overlaps. Any ideas?
