The kernel performs OK until when i try to make apache2 from ports, It gets to this stage: checking for va_copy... yes checking whether stdint.h conforms to C99... yes checking whether strstr works in linear time... Then the Kernel segfaults with: Freebsd kernel: SIGSEGV: pmap=0xc191ecac p=conftest va=0x0 ftype=0x1 eip=0x2814efb4 err=4 *pte=0x0000000000000000 The system then locks up totally.
