Yeah, I'm using the spca5xx-20060501.tar.gz release.
The error you reported is simply in a "printk" line --
commenting it out will allow the module to compile.
However, when running the module together with
ppp traffic will always crash the kernel with a dump
something like this:
Unable to handle kernel NULL pointer dereference at virtual address 00000000

I'm using the -ts9 kernel with the patch to numa.c from TS.
I assume that the "pc" in the above dump is the program counter;
that address is somewhere in consistent_alloc.
How do I go about debugging this?
Andrew.
