To all of you that have been asking lately........
I have finally uploaded the tar image of the directory I am using for the
8xx updates. I have not checked in all of these changes to CVS as I
still have to do my best to ensure I have not broken something.
Some of you have indicated you wish to contribute modifications, so please
implement them against this source base and send me the patches or files.
When you use this kernel, I would appreciate hearing of success as well
as failure.
For those of you that use the embedded system as I do (single user shell),
I have added the 'standalone shell' that creates a new thread for starting
the shell. This enables proper signal handling so tty control signals work.
I don't know if this will boot to multi-user properly, so if you do not want
this behavior go into init/main.c and undefine SASH.
The tar file is on linuxppc.cs.nmt.edu in the embedded directory, called
embedded-2.2.5.tgz.
Have fun.

Hi !
Is there a homepage or somthing, where I can find information about
available 8xx board designs ?

I just merged my local changes with the 2.2.5-embedded sources.
I get an error when starting init. (Booting from nfs.)
It just says:
Freeing unused kernel memory: 32k init
put_dirty_page: page already exists
and hangs. I tried to disable the SASH thing, but that made no difference.
I haven't had time to check more, gotta go home now.
Do you have any idea?

Ummm.....it would help if I knew a little more about what you are using.
Like, what kind of board and the kernel configuration?
I would see a similar problem when I would configure IDE and not
configure PCI. This is because the IDE probes (and other I/O in/out
operations) map to real memory locations and tend to write on top of
kernel data structures. This is my only guess without more information.

I'm gonna look into it myself now, i just wondered if it was something
you've seen before and knew how to fix. It worked in 2.2p7.

I've turned of both IDE and PCI (i hope, better check).

I found it. The new version had a nifty clear_page that did datacache
tricks to clear memory. This fails splendidly when the datacache is
disabled, which i had due to some hw problems.
It works great now!
