My last message was not very information-packed, but I'll do better this time. One suggestion I had was to rebuild my linux LKM (as the problem happened 100% when running linux stuff)... I've done this, and it has not helped. sources are spanking new 2.2.6-stable. World was last made, um, may 11. M/B is an ASUS with BX chipset. RAM is SDRAM, non-parity. Disks are seagate cheetah and an old 1 GB conner from a sun. Here's my dmesg: FreeBSD 2.2.6-STABLE #0: Sun May 24 12:37:04 CDT 1998 root@couatl.uchicago.edu:/usr/src/sys/compile/COUATL CPU: Pentium Pro (400.91-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x651 Stepping=1 Features=0x183f9ff,,MMX,> real memory = 134217728 (131072K bytes) avail memory = 120303616 (117484K bytes) Probing for devices on PCI bus 0: chip0 rev 2 on pci0:0: 0 chip1 rev 2 on pci0:1: 0 chip2 rev 2 on pci0:4:0 chip3 rev 1 on pci0:4:1 chip4 rev 1 int d irq 9 on pci0:4:2 chip5 rev 2 on pci0:4:3 de0 rev 32 int a irq 9 on pci0:10:0 de0: ZNYX ZX34X 21140A [10-100Mb/s] pass 2.0 de0: address 00:c0:95:f8:15:2f ahc0 rev 1 int a irq 15 on pci0:11:0 ahc0: aic7860 Single Channel, SCSI Id=7, 3 SCBs ahc0 waiting for scsi devices to settle ahc0: target 0 Tagged Queuing Device (ahc0:0:0): "SEAGATE ST34501N 0017" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 4339MB (8887200 512 byte sectors) ahc0: target 1 Tagged Queuing Device (ahc0:1:0): "CONNER CFP1060S 1.05GB 2035" type 0 fixed SCSI 2 sd1(ahc0:1:0): Direct-Access 1013MB (2074880 512 byte sectors) Probing for devices on PCI bus 1: vga0 rev 0 int a irq 11 on pci1:0:0 Probing for PnP devices: CSN 1 Vendor ID: CTL0028 [0x28008c0e] Serial 0x1008415c pcm1 (SB16pnp sn 0x1008415c) at 0x220 irq 5 drq 1 flags 0x15 id 16 Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <16 virtual consoles, flags=0x0> 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 psm0 at 0x60-0x64 irq 12 on motherboard psm0: model Generic PS/2 mouse, device ID 0 pcm0 not found at 0xffffffff fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: FIFO enabled, 8 bytes threshold fd0: 1.44MB 3.5in wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (atapi): , removable, accel, iordis wcd0: 689Kb/sec, 128Kb cache, audio play, 256 volume levels, ejectable tray wcd0: no disc inside, unlocked aha0 not found at 0x330 npx0 flags 0x1 on motherboard npx0: INT 16 interface Crashes occur 100% instantly when running any linux programs.

(others use my machine, so perhaps at other times they were running some linux whatever, not me.) One thing that has changed with the machine is the ethernet card. I had an intel card (100+) go belly-up a couple of days ago and replaced it with the ZNYX which was kicking around. (the intel card got *really* slow over the course of a couple of days, dropping down to ftp transfers of 3kB/sec... replacing it with the ZNYX made the problem go away immediately...) just tried replacing the intel ethernet and the problem still exists, so i don't think this is pertinant. I have a 128MB core file with debugging symbols.
