Yep.

Gnrf, I've always seen a special-char on the end of the command-line
when booting 2.4 and I've ignored it... I also always edit the
params.txt with vim, which automatically puts a cr-lf after the last
line, so that's why it works for me.
I would blame linexec, too, as it is really ugly ;-)
But I can't see what is wrong in setup_linux_params in boot.cpp
at the moment:
http://cvs.zerfleddert.de/cgi-bin/viewcvs.cgi/linexec-j720/boot.cpp?view=markup
But I certainly wonder what the 3 ? are:
// must be at least +3!! 1 for the null and 2 for the ???

As the kernel is now able to initialize pcmcia-slots by itself, the
initrd is theoretically no longer needed, and the kernel needs to know
where the root-fs is.

Hm, no idea. But from your log, it looks like it's triggered by the
initrd.
