List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Has anyone had any luck booting from a linux filesytem on a USB pen drive running 2.6? I am running kernel 2.6.9 that is programmed into flash and am trying to boot from a root filesystem on a USB pen drive. I am using the kernel command line option "root=/dev/sda1". I am able to NFS boot my system, and then mount my pen drive, and can see all of the files fine. However, it tells me that I have an invalid root option if I try setting root to /dev/sda1. I understand under 2.4 there is a patch that keeps trying to mount the sda1 device with time delays in between each try. I tried that, but it didn't help. I also tried the 2.6 patch that keeps a list of ready devices, and that didn't work. I was trying to do this without a ramdisk, but so far it looks like I'll have to use one after all.
