Having experienced a number of crashes with Xfree 4.0 with 2.4 kernels, that I wasn't getting with 2.2 kernels, a quick search on the xfree Xpert mailing list reveals this:

This is a long-standing problem with 2.3 and 2.4 SMP kernels. I believe it is a kernel bug and isn't the XFree86 project's problem. The problem does not exist on 2.2 SMP kernels nor on 2.3/4 UP kernels. The symptoms are random segfaults in perfectly fine XFree86 code. ---------------------------------------------------------------------
Anyone looking into this?
