Re: Hangs using X

:I've experiencing hangs on my DFly box, since march 28, 29 or 30, I don't
:remember when I cvsuped that time. I have cvsuped 2 or 3 times after that
:days and the problem is still there.
:I have just take times and it hangs after an hour and a half using X:
:GNOME 2.10 running Gaim, XMMS sometimes, XChat, and Firefox. Someone told
:me on IRC that he was having the same trouble with his nVidia card, but I
:don't have nVidia card or drivers for it.
:I can't get any message from console 'cause it just hangs and reboots in
:the moment.

    Do you have your system setup to dump core?  The requirements are:

    * That your swap space be at least as large as main memory

    * Add a dumpdev line to your /etc/rc.conf, e.g.  dumpdev="/dev/ad0s1b"

    * The /var/crash is on a filesystem with enough space to hold the dump
      (the size of main memory).  You can move /var/crash to another
      filesystem, e.g. /home, with a softlink if it isn't big enough.  e.g.:

      cpdup /var/crash /home/var.crash
      rm -rf /var/crash
      ln -s /home/var.crash /var/crash

    Another option if you have a second machine is to connect up the
    serial ports with a null modem cable and monitor the console via the
    serial port.  To do this you, once it is set up, interrupt the boot
    sequence at the loader menu (option 6) and then type 'boot -h' so the
    kernel uses the serial port for its console.

    I'd like to pounce on this issue ASAP, especially if its repeatable.  I
    would appreciate it if others could try testing for this problem too.

    Guillermo, your 'dmesg' output would also be helpful (but I'm mainly
    counting on you being able to get a core dump for us to find this one).
