Whate kind of kernel errors cause an Segmentation Fault

[Kári Davíðsson]

Well he asked what kind of kernel error causes segfault.
If I am not wrong returning EFAULT, e.g. from driver causes
the kernel to send signal 11 (SIGSEGV) to the application
which has default signal handler that causes the application
to crash.
