I'm using XFree86 version 4.0.1 on the machine that exhibited the problem. When I tried going back to version 3.3.6, the silo over- flows went away. (Unfortunately, I had to go back to 4.0.1, as the XF86_SVGA server I need to use in 3.3.6 to run my ATI Xpert 128 video card has several nasty bugs, but that's another story.) I also get solid, error-free serial I/O if I escape out of X and display high-speed serial output directly to the monitor. Let me also mention, for the record, that I checked my null modem serial cable very carefully with a continuity tester, and the cable is definitely wired OK (it swaps RTS and CTS, for example). This presumably leaves open the question of whether the problem is due to a bug in XFree86-4.x itself, or if XFree86-4.x is innocently tickling some FreeBSD kernel bug.
