It does not seem, however, to be Xorg itself; the crashes also occur when X is not in use. I did not rebuild my kernel around that time. I hope that I have provided enough information, if I have not, I can gladly get more. I have attached my kernel configuration, my uname -a output is: FreeBSD jhengis.vistua.com 6.2-RELEASE-p5 FreeBSD 6.2-RELEASE-p5 #3: Sat Jun 2 12:45:19 EDT 2007 root@jhengis.vistua.com:/usr/obj/usr/src/sys/BORODIN i386 (The recent datestamp on this kernel is because I rebuilt it with debug information, so I could catch the dump.) You can get the complete contents of /var/crash from ftp://anonymous@jhengis.vistua.com/pub/crash.tar.bz2 Any help would be greatly appreciated! --John --Boundary-00=_iUebGdTa5TzQtqJ Content-Type: text/plain; charset="us-ascii"; name="BORODIN" Content-Transfer-Encoding: 7bit Content-Description: Kernel Configuration Content-Disposition: attachment; filename="BORODIN" machine i386 cpu I686_CPU ident BORODIN # To statically compile in device wiring instead of /boot/device.hints #hints "GENERIC.hints" # Default places to look for devices. makeoptions DEBUG=-g options SCHED_4BSD # 4BSD scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options INET6 # IPv6 communications protocols options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories options MD_ROOT # MD is a potential root device options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_GPT # GUID Partition Tables. options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options COMPAT_FREEBSD5 # Compatible with FreeBSD5 options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI options KTRACE # ktrace(1) support options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options KBD_INSTALL_CDEV # install a CDEV entry in /dev options ADAPTIVE_GIANT # Giant mutex is adaptive. device apic # I/O APIC # Bus support. device eisa device pci # Floppy drives device fdc # ATA and ATAPI devices device ata device atadisk # ATA disk drives device atapicd # ATAPI CDROM drives device atapifd # ATAPI floppy drives options ATA_STATIC_ID # Static device numbering device atapicam # SCSI peripherals device scbus # SCSI bus (required for SCSI) device ch # SCSI media changers device da # Direct Access (disks) device cd # CD device pass # Passthrough device (direct SCSI access) device ses # SCSI Environmental Services (and SAF-TE) device atkbdc # AT keyboard controller device atkbd # AT keyboard device psm # PS/2 mouse device sc device agp device kbdmux # keyboard multiplexer device vga # VGA video card driver device splash # Splash screen and screen saver support options VESA options VGA_WIDTH90 options SC_PIXEL_MODE # PCI Ethernet NICs that use the common MII bus controller code. # NOTE: Be sure to keep the 'device miibus' line in order to use these NICs! device miibus # MII bus support device re # RealTek 8139C+/8169/8169S/8110S device rl # RealTek 8129/8139 # Pseudo devices. device loop # Network loopback device random # Entropy device device ether # Ethernet support device ppp # Kernel PPP device tun # Packet tunnel. device pty # Pseudo-ttys (telnet etc) device md # Memory "disks" device gif # IPv6 and IPv4 tunneling device faith # IPv6-to-IPv4 relaying (translation) device bpf # Berkeley packet filter # USB support device ehci # EHCI PCI->USB interface (USB 2.0) device usb # USB Bus (required) device ugen # Generic device uhid # "Human Interface Devices" device ulpt # Printer device umass # Disks/Mass storage - Requires scbus and da # USB Ethernet, requires miibus #device rue # RealTek RTL8150 USB Ethernet device atapicam --Boundary-00=_iUebGdTa5TzQtqJ--
