good learning experience for Linux

good learning experience for Linux

[Steven Blakeslee]

I sent a message earlier today about getting a "swap_dup: Bad swap file
entry 0e18d55c" error.  I found the problem and fixed it and wanted to share
it with people who are still learning this stuff, like myself.

After 2 days of pounding on my head I found the file
Documentation/powerpc/cpu_features.txt  It explained how the file
arch/ppc/kernel/cputable.c has a list of the known powerPC PVRs(processor
version register).  The 8248 was not in there so it was using a default
entry.  That was the cause of my problems.  I added a new entry for the 8248
and all is working.  My lesson was a little research makes things much
nicer.  Lesson learned.

So, is this already in the latest kernel sources?  If not,
have you considered sending in a patch?

I still have so more to do like verifying FEC and PCI.  Also I did it on 2.4
which I believe is done or close to being.  I can provide a patch when I am
done.
