Re: BUG in _nv026629rm while starting X on kernel 2.6.35
I briefly looked at a reproduction of what likely is the same (or a very similar) problem a few weeks ago. In my case, at least, the problem appeared to be that the kernel hadn't relocated one of the module's read-only data sections correctly, which caused a crash when the NVIDIA driver accessed a string located in that section.
I didn't get a chance for an in-depth investigation at the time. I did try to determine if the problem lay with the kernel, the toolchain, or something else entirely, but had trouble building a working kernel on the system. There's a bug filed internally, and I plan on revisiting it. Unfortunately, given the problem's nature and the low number of reports, this likely won't happen soon.
