Hi, I just got my 2.4 kernel running on my 860 board. However I have now encountered a new problem "Kernel panic: VFS: Unable to mount root fs on 01:00".
There are lots of posts regarding this problem but no one "seems" to have posted a solution and then claim afterwards that it works ... so I regretfully must ask again ... Here's some info about my setup: 1.) ppcboot 1.1.6 2.) bootargs "root =/dev/ram rw" 3.) CONFIG_BLK_DEV_LOOP=y 4.) CONFIG_BLK_DEV_RAM=y 5.) CONFIG_BLK_DEV_RAM_SIZE=4096 6.) CONFIG_BLK_DEV_INITRD=y 7.) Tftpboot ... downloads my kernel to 0x100000 8.) setenv loadaddr 0x00200000 9.) setenv bootfile simple-initrd 10.) tftpboot ... down load init rd 11.) imi 0x00100000 0x00200000 ... images are ok 12.) bootm 0x00100000 0x00200000 ... kernel starts ... 13.)
