Wow, that saved me a lot of time. I just ran into the same issue and was close to getting mad over the effect. Maybe the commit is only that big because cvs-to-git conversion merged too much into a single commit. I can't imagine that such a huge change is done in one step. >=20 > Quoted below is my first mail to the list, with few details about the > problem.

At least it is a critical one as it makes kernel module debugging nearly impossible. I'm preparing a LinuxCon talk about how cool kernel debugging with gdb and qemu can be - looks like I have to skip this part... ;) If there is anything to be done that could help analyzing the issue, please let us know.
