5.1 panics on a Challenge S

Hi,

I tried to install 5.1 on my Challenge S and the kernel panics just
after the 'panel0' line, see below for full output. The panic happens
with both the INSTALL and GENERIC kernels on a Challenge S but both
kernels boot normally on an Indy. I've built a custom kernel with the
'panel' line commented out of the config, that cures the panic and the
kernel then boots normally.
