Re: EMC and new Redhat.

No, 2.2.12 WILL NOT work. Even if RedHat did box up a 2.2.10 kernel, I wouldn't use it because often patches don't work well
with RedHat kernels (because they are modified). You can get the full gernel sources from ftp.kernel.org in a tarball called
linux-2.2.10.tar.gz somewhere on the server. If you can't find it, tell me and I'll get a link. Here's what you do once you get
it:

in /usr/src there should be a directory 'linux' and a directory 'linux-2.2.12'. Delete the linux directory for now. It is only
a link to the linux-2.2.12 directory and we don't want things to get ugly.

then, run
tar xzvf linux-2.2.10.tar.gz
in the /usr/src directory

change the name of the 'linux' directory that that untarred into to something better, lets say 'linux-2.2.10'

make a link for /usr/src/linux with
ln -s linux-2.2.10 linux
in the /usr/src/directory

you can even copy the .config from /usr/src/linux-2.2.12 to /usr/src/linux-2.2.10 if you want (to keep your old config)

Then follow RT instructions and the ones on EMCs site.
You MAY need to fiddle with the directory names a bit because beta11 untars into /usr/src/beta11/rtl and EMC looks for it in
/usr/src/rtl. for this, just do a "ln -s /usr/src/beta11/rtl /usr/src/rtl" to fix that. You also need to do some Makefile
editing in /usr/src/rtl and subdirs, but that is a topic for another day.
