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.
