Why would you btw want to use an initramfs instead of a real flash file
system? Initramfs uses more RAM and typically boots slower than
E.G. squashfs.
Ryan> When I run this I get the following problems:
Ryan> Bootline: Linux/PowerPC load: console=ttyS0 ip=on
Ryan> Bad trap at PC: 4801f1b4, SR: 2d000, vector=2010
Ryan> Bootline: Linux/PowerPC load: console=ttyS0 ip=on root=/dev/ram
Ryan> Bad trap at PC: 4801f1b4, SR: 2d000, vector=2010
How big is your cpio.gz / zImage?
Ryan> I then tried to just get to a shell by doing the following:
Ryan> Bootline: Linux/PowerPC load: console=ttyS0 ip=on rdinit=/bin/sh
Ryan> Bootline: Linux/PowerPC load: console=ttyS0 ip=on root=/dev/ram
Ryan> rdinit=/bin/sh
Ryan> Bad trap at PC: 4801f1b4, SR: 2d000, vector=2010
Ryan> init has generated signal 5 but has no handler for it
So it gets all the way to init? Please paste the complete serial output.
Are you using hardware or software floating point in buildroot? please
paste your buildroot .config.
Ryan> Kernel panic - not syncing: Attempted to kill init!
Ryan> Call Trace:
Ryan> [cf831d80] [c0005f88] show_stack+0x48/0x15c (unreliable)
Ryan> [cf831db0] [c0220c80] panic+0x94/0x174

Enable CONFIG_KALLSYMS so you get a proper symbolic backtrace.
