The only constant seems to be a size at or above 160GB. http://lists.freebsd.org/pipermail/freebsd-questions/2004-June/050234.html http://lists.freebsd.org/pipermail/freebsd-current/2004-July/031154.html I've tried everything mentioned there, including a new drive cable (certified for UDMA133), disabling ACPI, etc. The only soultion I found was using atacontrol to drop to UDMA33. >From dmesg.boot: CPU: AMD Athlon(tm) XP 2600+ (1909.03-MHz 686-class CPU) Origin = "AuthenticAMD" Id = 0x6a0 Stepping = 0 Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MM atapci0: <VIA 8237 UDMA133 controller> port 0xcc00-0xcc0f at device 15.0 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata0: [MPSAFE] ata1: at 0x170 irq 15 on atapci0 ata1: [MPSAFE] GEOM: create disk ad0 dp=0xc4454360 ad0: 58643MB <HDS722580VLAT20> [119147/16/63] at ata0-master UDMA100 GEOM: create disk ad2 dp=0xc4449c60 ad2: 238475MB <WDC WD2500JB-00FUA0> [484521/16/63] at ata1-master UDMA100 >How-To-Repeat: Install a UDMA100 or 133 drive >- 160GB on a VIA KT600 board w/ an 8235 or 8237.
