It gets through two or three builds and then crashes. Unfortunately the crash seems to be completely undebuggable. It drops into DDB> but the serial port is completely screwed up and I can't type. Hitting gives me colons and semicolons at db> prompt. Changing baud rates does not seem to help. This has occured twice. I am going to try dropping back to a standard console to see if I can get better debugging. I don't know if this is KSE related or not. I've included the serial console output. -Matt Fatal trap 12: page fault while in kernel mode cpuid = 0; lapic.id = 01000000 fault virtual address = 0xb fault code = supervisor write, page not present instruction pointer = 0xd35:0xe Fatal trap 12: page fault while in kernel mode cpuid = 0; lapic.id = 01000000 fault virtual addrepsasn i=: t nceode! p= cs puupeirdv =is o1r; lraeapdi n c, .pidag e= n0o0t00 0pr00es0e tDe niugnsgetrru("cptaioninc "p)oi Stopped at Debugger+0x46: xchgl %ebx,in_Debugger.0 db> ;;: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
