  having just got back from vacation, i may have missed some of the latest
developments.  i just did a "bk pull" from the linuxppc-2.5 tree, rebuilt
the kernel for my 8xx board and, just like before i left, the kernel hung
almost immediately upon booting:

Linux/PPC load: console=ttyS0,9600 rw root=/dev/ram0 init=/sbin/minit
Uncompressing Linux...done.
Now booting the kernel
(hang)

should i be expecting this?  once upon a time, of course, i got all the
way to user space before the hang.  have there been some recent patches to
cause this latest behaviour?  i haven't messed with the config file in
quite some time.  should i?

What probably happened is that you don't have a UART driver selected.
I've had my best luck with CONFIG_SERIAL_CPM, so you might want to try
that.

i selected that, but still no luck -- kernel still hangs almost
immediately -- but there may be other issues here.

I haven't had time to look into this yet, in part because I just don't
know how well to trust my h/w, but to get SMC1 console working (RPX
Lite) I need to enable both SCC1 and SMC1.  For your board, I would
recommend enabling all of the consoles.

And in case others were wondering, the old driver has a different set of
issues, at least on my hw, it doesn't see input (and/or it causes a
livelock at boot, I haven't tried again in a while).
