I just installed an old compaq desktop that I intend to use as a webserver. I haven't installed anything on it yet, it's using vanilla 4.2-RELEASE. Twice now, I've booted it and left it running, intending to ssh in and work on it, except I've found that I couldn't because it's crashed on me. It has literally nothing running except the standard daemons (ntpd, sshd, httpd...) when this (faithfully transcribed) happens: uvm_fault(0xd687875c, 0xcfc70000, 0, 1) -> e kernel: page fault trap, code=0 Stopped at pmap_enter+0xaf: movl 0(%edx,%eax,4),%eax ddb> trace pmap_enter(d69c7a2c, 1c022000, 2353000,5,20,1c027000,da433ea4,0) at pmap_enter+0xaf uvm_fault(d687875c,1c023000,0,1,da3efea0) at uvm_fault+0xd0c trap() at trap+0x269 --- trap (number 6) -- 0x1c023261: ddb> ps PID PPID PGRP UID S FLAGS WAIT COMMAND 1311 17544 648 0 2 0 sh *22991 17544 648 0 7 0 sh 17544 14843 648 0 3 0x80 pause sh 14843 27930 648 0 3 0x4080 piperd sh 22189 648 648 0 3 0x4080 piperd mail 15690 648 648 0 3 0x4080 piperd tee 27930 648 648 0 3 0x4080 pause sh 648 11321 648 0 3 0x4080 pause sh 11321 4468 4468 0 3 0x80 piperd cron 6321 1 6321 0 3 0x4082 ttyin getty 16590 1 16590 0 3 0x4082 ttyin getty 28581 1 28581 0 3 0x4082 ttyin getty 29125 1 29125 0 3 0x4082 ttyin getty 13313 1 13313 0 3 0x4082 ttyin getty 4468 1 4468 0 3 0x80 select cron 30525 1 30525 0 3 0x80 select sshd 14729 5611 5611 67 3 0x180 netcon httpd 11199 5611 5611 67 3 0x180 netcon httpd 20250 5611 5611 67 3 0x180 netcon httpd 7697 5611 5611 67 3 0x180 netcon httpd 1843 5611 5611 67 3 0x180 netcon httpd 24949 1 24949 0 3 0x40180 select sendmail 8752 1 8752 0 3 0x180 select inetd 5611 1 5611 67 3 0x180 select httpd 20884 29121 29121 83 3 0x180 poll ntpd 29121 1 29121 0 3 0x80 poll ntpd 13148 1 12414 73 2 0x180 syslogd 12414 1 12414 0 3 0x88 netio syslogd 3628 1 3628 77 3 0x180 poll dhclient 14719 1 24228 0 3 0x82 poll dhclient 16 0 0 0 3 0x100200 crypto_wait crypto 15 0 0 0 3 0x100200 aiodoned aiodoned 14 0 0 0 3 0x100200 syncer update 13 0 0 0 3 0x100200 cleaner cleaner 12 0 0 0 3 0x100200 reaper reaper 11 0 0 0 3 0x100200 pgdaemon pagedaemon 10 0 0 0 3 0x100200 pftm pfpurge 9 0 0 0 3 0x100200 usbevt usb4 8 0 0 0 3 0x100200 usbevt usb3 7 0 0 0 3 0x100200 usbevt usb2 6 0 0 0 3 0x100200 usbevt usb1 5 0 0 0 3 0x100200 usbtsl usbtask 4 0 0 0 3 0x100200 usbevt usb0 3 0 0 0 3 0x100200 bored syswq 2 0 0 0 3 0x100200 kmalloc kmthread 1 0 1 0 3 0x4080 wait init 0 -1 0 0 3 0x80200 scheduler swapper
So what's the deal? Is this a bug? Is it flakey hardware? I mixed and matched the RAM a bit, could that be it? Could the RAM be slightly unseated? I found this, which has the same issue: http://archive.netbsd.se/?ml=openbsd-newbies&a=2005-08&m=1127711 dmesg: OpenBSD 4.2 (GENERIC) #375: Tue Aug 28 10:38:44 MDT 2007 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: AMD Duron(tm) Processor ("AuthenticAMD" 686-class, 64KB L2 cache) 902 MHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR real mem = 528052224 (503MB) avail mem = 502943744 (479MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 05/03/01, BIOS32 rev. 0 @ 0xfa100, SMBIOS rev. 2.3 @ 0xf0000 (19 entries) bios0: vendor Compaq version "786K3" date 05/03/2001 bios0: Compaq Presario 5100CA 470013-866 pcibios0 at bios0: rev 2.1 @ 0xfa040/0x1000 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfa040/128 (6 entries) pcibios0: PCI Interrupt Router at 000:20:0 ("VIA VT82C686 ISA" rev 0x00) pcibios0: PCI bus #1 is the last bus bios0: ROM list: 0xc0000/0x10000 0xe9000/0x3000! 0xec000/0x4000! acpi at mainbus0 not configured cpu0 at mainbus0 pci0 at mainbus0 bus 0: configuration mode 1 (no bios) pchb0 at pci0 dev 0 function 0 "VIA VT8363 Host" rev 0x81 ppb0 at pci0 dev 1 function 0 "VIA VT8363 AGP" rev 0x00 pci1 at ppb0 bus 1 vga1 at pci1 dev 0 function 0 "S3 ProSavage KM133" rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) dc0 at pci0 dev 3 function 0 "ADMtek AN983" rev 0x11: irq 3, address 00:04:5a:60:f5:5b acphy0 at dc0 phy 1: AC_UNKNOWN 10/100 PHY, rev. 0 ohci0 at pci0 dev 4 function 0 "NEC USB" rev 0x41: irq 10, version 1.0 ohci1 at pci0 dev 4 function 1 "NEC USB" rev 0x41: irq 11, version 1.0 ehci0 at pci0 dev 4 function 2 "NEC USB" rev 0x02: irq 3 usb0 at ehci0: USB revision 2.0 uhub0 at usb0: NEC EHCI root hub, rev 2.00/1.00, addr 1 pcib0 at pci0 dev 20 function 0 "VIA VT82C686 ISA" rev 0x22 pciide0 at pci0 dev 20 function 1 "VIA VT82C571 IDE" rev 0x10: ATA66, channel 0 configured to compatibility, channel 1 configured to compatibility wd0 at pciide0 channel 0 drive 0: <QUANTUM FIREBALLlct20 40> wd0: 8-sector PIO, LBA, 38172MB, 78177792 sectors wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 4 atapiscsi0 at pciide0 channel 1 drive 1 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0: <SONY, CDU5211, YYS2> SCSI0 5/cdrom removable cd0(pciide0:1:1): using PIO mode 4, Ultra-DMA mode 2 uhci0 at pci0 dev 20 function 2 "VIA VT83C572 USB" rev 0x10: irq 11 uhci1 at pci0 dev 20 function 3 "VIA VT83C572 USB" rev 0x10: irq 11 viaenv0 at pci0 dev 20 function 4 "VIA VT82C686 SMBus" rev 0x30: HWM disabled: 32-bit timer at 3579545Hz auvia0 at pci0 dev 20 function 5 "VIA VT82C686 AC97" rev 0x20: irq 10 ac97: codec id 0x41445348 (Analog Devices AD1881A) ac97: codec features headphone, Analog Devices Phat Stereo audio0 at auvia0 usb1 at ohci0: USB revision 1.0 uhub1 at usb1: NEC OHCI root hub, rev 1.00/1.00, addr 1 usb2 at ohci1: USB revision 1.0 uhub2 at usb2: NEC OHCI root hub, rev 1.00/1.00, addr 1 isa0 at pcib0 isadma0 at isa0 pckbc0 at isa0 port 0x60/5 pckbd0 at pckbc0 (kbd slot) pckbc0: using irq 1 for kbd slot wskbd0 at pckbd0: console keyboard, using wsdisplay0 pcppi0 at isa0 port 0x61 midi0 at pcppi0: <PC speaker> spkr0 at pcppi0 lpt0 at isa0 port 0x378/4 irq 7 npx0 at isa0 port 0xf0/16: reported by CPUID; using exception 16 pccom0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo fdc0 at isa0 port 0x3f0/6 irq 6 drq 2 usb3 at uhci0: USB revision 1.0 uhub3 at usb3: VIA UHCI root hub, rev 1.00/1.00, addr 1 usb4 at uhci1: USB revision 1.0 uhub4 at usb4: VIA UHCI root hub, rev 1.00/1.00, addr 1 biomask ff6d netmask ff6d ttymask ffef pctr: user-level cycle counter enabled mtrr: Pentium Pro MTRR support dkcsum: wd0 matches BIOS drive 0x80 root on wd0a swap on wd0b dump on wd0b WARNING: / was not properly unmounted
