Hello again linuxsh-dev,

I am now having some trouble getting the latest CVS kernel to boot. It
gets past the Linux banner and then generates hundreds of lines of
paging errors. Here is the GDB output:

And so on indefinitely through every page in the memory space. I get the
same results with Linux-2.4.0-test6 and the CVS kernel. Anyone seen this
before or know what may cause it?

Thanks,
