Looks like si is garbage: > fault virtual address = 0x211e6d36 is most likely the value of si at the time of the crash. It's nowhere near kernel memory (which starts at 0xc0000000). If / when you get a dump, show me the backtrace and the value of x, y and udev (as reported by gdb operating on the recovered core) > > How do you build your kernels - 'make buildkernel' or manually? > Always make buildkernel.
