This is a plea for help, ideas, what have you... I recently converted my big Linux box, voyager.abac.com, over to FreeBSD. I started out with 2.2.1-RELEASE, then went to the 4/22 -SNAP release, and finally to 2.2.2-RELEASE. Unfortunately, all 3 have been falling victim to a rather bizarre and extremely frustrating crashing problem. What happens is that the system will be up and running fine, and will all of a sudden just *die*. Nothing unusual will appear in the log files. The system will simply become unresponsive. Even at the console, I can type and the characters will echo back to me, but the system will not process them. Even control characters -- if I hit Ctrl-C, it'll print ^C on the screen. So, I can never tell *why* it crashed... it just up and dies on me. The system is a Pentium 200 with a Tyan Titan VX motherboard. It has 128 MB of RAM, a 3Com 3C905-TX Fast Etherlink XL (the 10/100 MBps version) ethernet card, an Adaptec 2940 SCSI controller (the normal version, not wide or ultra-wide), a Cirrus Logic GD5430 PCI video card with 2 MB of video RAM, and a Logitech Bus Mouse. There are 4 hard drives and one tape drive hooked up to the SCSI chain. In order, they are: SCSI 0 - Quantum ProDrive 540 MB; SCSI 1 - Quantum Fireball 2.1 GB; SCSI 2 - Quantum Trailblazer 850 MB; SCSI 3 - Quantum Fireball 1 GB; and SCSI 5 - Conner 4 GB QIC-Wide tape backup drive. There is also one Western Digital 420 MB IDE drive hooked up as a single drive on the secondary IDE chain (the primary IDE has no drives on it). The 540 MB drive has /, the 2.1 GB has /home, the 850 MB has /ftp, and the 1 GB has /usr. The 420 MB IDE drive is solely a swap drive. The SCSI Controller is using a slightly older revision of the BIOS, v1.21. I have a v1.23 chip on the way from Adaptec, which is the latest one available. As if that weren't enough info, I'm also including my kernel configuration file, in case that might prove useful. I suspect that there *could* be something in there that's doing it, because if I'm remembering correctly, the system was up for about 2 days running on the Generic kernel, before I compiled a custom one (before I knew how to). Any ideas any of you can provide about this would undoubtedly be extremely helpful. Thanks very much in davance. Here's the kernel config file: # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # For more information read the handbook part System Administration -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # <URL:http://www.FreeBSD.ORG/>; # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file. If you are # in doubt as to the purpose or necessity of a line, check first in LINT. # # $Id: GENERIC,v 1.77.2.4 1997/02/22 20:31:24 joerg Exp $ machine "i386" cpu "I586_CPU" ident VOYAGER maxusers 512 options INET #InterNETworking options FFS #Berkeley Fast Filesystem options MSDOSFS #MSDOS Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 [KEEP THIS!] options SCSI_DELAY=5 #Be pessimistic about Joe SCSI device options BOUNCE_BUFFERS #include support for DMA bounce buffers options UCONSOLE #Allow users to grab the console options FAILSAFE #Be conservative options USERCONFIG #boot -c editor options VISUAL_USERCONFIG #visual boot -c editor #ADD THIS: options "NMBCLUSTERS=6000" options DIAGNOSTIC # Used to help catch errors in certain types of programs # when they compile, won't hurt anything, and can help. options "CHILD_MAX=128" options "OPEN_MAX=128" options "MAX_USERS=300" options "FD_SETSIZE=4096" options "MAXMEM=131072" config kernel root on sd0 controller isa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 # A single entry for any of these controllers (ncr, ahb, ahc, amd) is # sufficient for any number of installed devices. controller ahc0 controller scbus0 device sd0 device od0 #See LINT for possible `od' options. device st0 device cd0 #Only need one of these, the code dynamically grows # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr # Enable this and PCVT_FREEBSD for pcvt vt220 compatible console driver #device vt0 at isa? port "IO_KBD" tty irq 1 vector pcrint #options PCVT_FREEBSD=210 # pcvt running on FreeBSD >= 2.0.5 #options XSERVER # include code for XFree86 #options FAT_CURSOR # start with block cursor # If you have a ThinkPAD, uncomment this along with the rest of the PCVT lines #options PCVT_SCANSET=2 # IBM keyboards are non-std # Mandatory, don't remove device npx0 at isa? port "IO_NPX" irq 13 vector npxintr # # Laptop support (see LINT for more options) # # PCCARD (PCMCIA) support #controller crd0 #device pcic0 at crd? #device pcic1 at crd? device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr device lpt0 at isa? port? tty irq 7 vector lptintr device mse0 at isa? port 0x23c tty irq 5 vector mseintr # Order is important here due to intrusive probes, do *not* alphabetize # this list of network interfaces until the probes have been fixed. # Right now it appears that the ie0 must be probed before ep0.
