You are correct... I am using the stuff from the 1.0 tar.  I will try the 2.4.2 patch 
tomorrow.  I saw that listed in the mail archives but from the context that looked 
like 
it was just your mtd hack.

I tried levels 1-9 in my testing all with various levels of sucess... seems like the 
odd 
compression levels were the ones that caused the oops but perhaps that was just a 
fluke.

Hmmm... I was afraid you would request that... That's gonna be a little difficult as 
this 
thing boots with a very minimal fs.  I have 1 meg to boot in and the kernel eats 
almost 
half most of the other half are the pcmcia modules.  I will see if I can duplicate the 
problem using an IDE boot with one of the 32Meg CF devices I have.  Thats probally a 
good 
test to do anyway.

What are all the files I need to put on my target to do a proper ksymoops decode and 
how 
do you get that info into ksymoops when the kernel hangs?

Hmmm... that could be the oops problem... I most definatly am NOT downing the 
interfaces.   
As soon as wget is done fetching the new image I jump dirctly into a boot. I'll give 
that 
a go tomorrow first since thats an easy change in my netboot script.

Oh and BTW.. I think you flubbed a cp command for the nbc-1.4.tar.gz file on 
donwload.linuxnetworx.com.  Its exactly the same size as the 2 other image files and 
gzip 
complains that the file dosen't have a proper compressed header.
