Hi Jonathan,
ok, it took a while, but finally I've tested wheezy with latest kernel
(linux-image-3.1.0-1-sparc64-smp) and the error's gone. It seems that

Sebastian

Just to make sure, is the kernel you are reading symbols from the
same build as the one that produced the message in dmesg?
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

The kernel modules gdb can use will be in .ko files scattered under the
linux/ source dir which you can find with commands like $ find . -name
.git -prune -o -name \*.ko -print Jonathan
sorry, last gdb entry was incomplete:
(gdb) list *(copy_to_user_state+0x9c0)

Good catch. It seems that debug kernels are only automatically built
for i386 and amd64 (presumably because those are the platfor

No, I haven't hit this, and alas I don't have a sparc to try it on.
