Basically the system locks up with the SCSI drive light on; Alt-Fn does nothing. There are no panic messages. The system: Gateway 2000 4DX2-66P PhoenixBIOS v4.03 GPCI 4.03.09 Motherboard: Anigma (?), Saturn Rev 3 chipset I believe Adaptec AHA-2940 Seagate Barracuda ST31250 Diamond Stealth 64 VRAM PCI DTC PCI IDE Controller WD Caviare 540MB IDE IDE CDROM SMC Elite Ultra SoundBlaster 16 (dmesg output is appended below) I install FreeBSD on the SCSI disk, which has no DOS partition. None of the IDE stuff is used, although the controller and disk are probed. The problem first occurred during installation (via NFS) while bin was being extracted. I turned the external cache off, and was able to install successfully. I built a custom kernel, booted it and tried to break it. It wasn't hard :-( The following: cd / tar -cf - usr | (cd /usr/local; tar -xvf -) caused a lock-up after about 5MB had been copied. /usr and /usr/local are both in their own partitions. I reduced the SCSI transfer rate to 5MHz, still with cache disabled, rebooted and tried again. It got a bit further - about 8MB copied. Again the system locked up, but this time the BIOS was hosed - I got "CMOS checksum bad" when I tried to reboot. Joy! I know that elsewhere the 2940 works well (ftp.cdrom.com). Has anyone any idea why it should bite me? Motherboard? If so, I'll change it. Timing problem due to fast disk? (7200rpm, 8ms - but I can't be the only person using one). BIOS? I'll be happy to try to obtain some diagnostics on this if someone can tell me how to go about it. iain dmesg output: FreeBSD 2.1.0-950726-SNAP #1: Thu Aug 3 21:29:26 BST 1995 root@nomad.nwpeople.demon.co.uk:/usr/src/sys/compile/NOMAD CPU: i486 DX2 (486-class CPU) Origin = "GenuineIntel" Id = 0x435 Stepping=5 Features=0x3 real memory = 16384000 (4000 pages) avail memory = 15069184 (3679 pages) Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <16 virtual consoles, flags=0x0> ed0 at 0x280-0x29f irq 10 maddr 0xd8000 msize 8192 on isa ed0: address 00:00:c0:8e:30:a1, type SMC8416C/SMC8416BT (16 bit) psm0 not found at 0x60 sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A lpt0 at 0x378-0x37f irq 7 on isa lpt0: Interrupt-driven port lp0: TCP/IP capable interface fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 72065B fd0: 1.44MB 3.5in wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): wd0: 515MB (1056384 sectors), 1048 cyls, 16 heads, 63 S/T, 512 B/S bt0 not found at 0x330 npx0 on motherboard npx0: INT 16 interface Probing for devices on the pci0 bus: configuration mode 2 allows 16 devices. chip0 rev 4 on pci0:0 chip1 rev 3 on pci0:2 ahc0 rev 0 int a irq 9 on pci0:3 ahc0: reading board settings ahc0: Reading SEEPROM...done. ahc0: 2940 Single Channel, SCSI Id=7, aic7870, 16 SCBs ahc0: Downloading Sequencer Program...Done ahc0: Probing channel A ahc0 waiting for scsi devices to settle ahc0: target 0 synchronous at 5.0MB/s, offset = 0xf (ahc0:0:0): "SEAGATE ST31250N 0006" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 973MB (1994037 512 byte sectors) vga0 rev 0 on pci0:4 pci0:5: vendor=0x1c1c, device=0x1, class=old [no driver assigned] pci0: uses 8392704 bytes of memory from 40000000 upto fffdffff. pci0: uses 256 bytes of I/O space from ff00 upto ffff. -- Iain Baird Network People International Tel: +44 (0)1732 743591
