PCMCIA Card, RTAI on PowerPC

[Andreas Plaickner]

Hello,

thanks a lot for the last help and advice to create a new
linux kernel, I appreciate it very much.

Now I have downloaded from DENX via anonymous ftp
the linux-2.4 kernel sources for PowerPC. I have created
a new kernel and tried to bring my PCMCIA interface to up
and it seems to work.

Now I wanted to patch this kernel to run RTAI on the Board.
Testing if the pach works with --dry-run I received the following:

patch --dry-run -b -z.PRE_RTAI -p1 < ../patch-denx-linux-2.4-D2002-09-26

Then I read that it is necessary to download the tree with revision date
2002-09-26. I did this one and created a kernel-image without rtai
like before, and I copied it to the board and this time the following
happened:

Kernel panic: Attempted to kill init!

What I would need is a combination of the source trees. The ideal would be
if i could patch the
kernel linux-2.4 from anonymous ftp on DENX as my PCMCIA card works with it.
Does
anyone have any suggestions what I could do to be able to patch this kernel?

Thanks a lot in advance for any suggestions.

Andreas
