Hi,
For the record, I've just merged powerpc.git from kernel.org and it has started working now! Clearly this means it was a kernel issue rather than a bootloader issue.
Regards,
Alex

Hi,
Sorry about the cross posting, but I'm not sure which list I should send to....
I'm trying to boot an up-to-date kernel on my MPC8323E-MDS-PB board, but I the console output stops early on during the kernel boot.
I'm running the latest u-boot (git://www.denx.de/git/u-boot-mpc83xx.git) with its default environment. The kernel is built from Paulus' powerpc.git, after checking out tag 2.6.21-rc5. The dtb is build from arch/powerpc/boot/dts/mpc832x_mds.dts with the latest compiler (git://www.jdl.com/software/dtc.git).
Has anyone else been here before...? If so I'd appreciate any help you can offer.
TIA,
Alex
