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? -tony --- E-Mail: Tony Gale If a nation expects to be ignorant and free, ... it expects what never was and never will be. -- Thomas Jefferson The views expressed above are entirely those of the writer and do not represent the views, policy or understanding of any other person or official body. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
