Great, thanks. i'll try this out when i have a chance to get back to playing with the device. Note also http://bugs.debian.org/582858 , which i just filed about initramfs-tools and a ubifs root while trying to make a slimmer initramfs. Fortunately, it turns out i can boot from my build of the 2.6.32-13 kernel if initramfs.conf contains MODULES=list (and i don't bother specifying any modules in the list). That seems to make the kernel+initramfs total < 4MiB, so maybe this will let me drop the netboot part of my current boot process. > You have to set the machine ID.

(something based on 2.6.20 or so?) it shipped with a kernel that identifies itself as: Linux version 2.6.32-00007-g56678ec (r...@msi-linux-build.marvell.com) (gcc version 4.1.2 20070925 (Red Hat 4.1.2-33.fa1)) #1 PREEMPT Mon Feb 8 03:49:55 PST 2010 > Anyway, you need: > > setenv mainlineLinux yes > setenv arcNumber 2659 > saveenv > reset Clint mentions that he tried this without success. I haven't tried it myself. --dkg
