How fix this? > To determine where the segfault is occurring, you will need to run things under gdb and obtain a backtrace. That said, if you are also seeing a kernel panic, I think it's more likely that the problem causing the kernel panic is resulting in the segfault and not the other way around. I would not expect a segfault within *any* userspace process to cause a kernel panic. - Mike
