2.6.31-10-rt image does not match source

[Invalid Opcode]

In Lucid, I expected that I should be able to download the source code for the linux-rt kernel image and recompile my own version that matches the image supplied in the repository. However, it appears that the source for the linux-image-rt is not the same that is found in the linux-headers-rt. So the binaries created do not match the ones supplied in the repository packages.

I submitted a post to the community hoping it was just operator error but nobody has responded,

My particular problem is that I need to compile some of the staging drivers and install in a stock Ubuntu Lucid linux-rt kernel.

If I download the source for the linux-image-rt, the staging drivers compile but fail on the insmod because of symbol table mismatches.

If I compile the staging drivers as an external module using the linux-headers-rt, the compile fails due to differences in the include directories.

Of course, this does not even address the problem that the linux-rt packages are revision behind the -generic...

I agree that this bug should be invalidated. It was caused by two operator errors:

1) Not running the apply-patchset
2) Not having /debian in the linux-rt source tree (while the rest of the source tree was there).

Following Alessio's steps above, I do get the debian directory that then allows me to run the apply-patchset. And the configs do match from there.

Just a quick follow up on how the /debian in the linux-rt source tree went missing - it gets cleaned out when your run a 'make distclean'. So I guess the fundamental problem all along is mixing kernel.org style kernel building with debian kernel building.
