I encounter the following problem: -------- If I generate a ramdisk.image.gz myself according to the initrd.txt kernel documentation < We'll describe the RAM disk method: 1) make sure you have a RAM disk device /dev/ram (block, major 1, minor 0) 2) create an empty file system of the appropriate size, e.g. # mke2fs -m0 /dev/ram 300 (if space is critical, you may want to use the Minix FS instead of Ext2) 3) mount the file system on an appropriate directory, e.g. # mount -t ext2 /dev/ram /mnt 5) copy all the files that are needed to properly use the initrd environment. Don't forget the most important file, /linuxrc Note that /linuxrc's permissions must include "x" (execute). 6) unmount the RAM disk # umount /dev/ram 7) copy the image to a file # dd if=/dev/ram bs=1k count=300 of=/boot/initrd 8) deallocate the RAM disk # freeramdisk /dev/ram < .. then the kernel doesn't start. entry 0x100000, phoff 0x34, shoff 0xf2864 phnum 0x1, shnum 0xa p_offset 0x10000, p_vaddr 0x100000, p_paddr 0x100000 p_filesz 0x532c, p_memsz 0xb1bc Loading at 0x10c000 Starting 0x11c000 loaded at: 0011C000 001271BC relocated to: 00100000 0010B1BC board data at: 00FF0000 00FF001C relocated to: 00200100 0020011C zimage at: 00122000 00182FEC initrd at: 00182FEC 001FE822 avail ram: 001FF000 01000000 Linux/PPC load: Uncompressing Linux...done.
