Yes, that's true. I've used the sources of debian via "apt-get source linux-image-2.6.32-5-sparc64-smp" and followed your instructions from there. I just had to activate the debug symbols in the .config file.Just to make sure, is the kernel you are reading symbols from the same build as the one that produced the message in dmesg?
I'll provide same info for a 3.x kernel, soon.Thanks, that's very useful.
It'll take a bit, I have to build a complete test bed...
