Running 5.2-RELEASE I've had some trouble with a pair of SATA drives I attached to the system. Whenever I'm doing heavy writing to the drives, they occasionally freeze the system for a couple of moments and spit out a message like: ad6: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=298264960 ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=299205856 ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=89954144 ad6: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=92024064 to the console. The controller is: atapci0: <SiI 3112 SATA150 controller> port 0xc000-0xc00f,0xbc00-0xbc03,0xb800-0xb807,0xb400-0xb403,0xb000-0xb007 mem 0xde002000-0xde0021ff irq 10 at device 11.0 on pci1 atapci0: [MPSAFE] ata2: at 0xde002000 on atapci0 ata2: [MPSAFE] ata3: at 0xde002000 on atapci0 ata3: [MPSAFE] The disks are: GEOM: create disk ad4 dp=0xc5f33660 ad4: 194481MB <Maxtor 6Y200M0> [395136/16/63] at ata2-master UDMA100 GEOM: create disk ad6 dp=0xc5f33360 ad6: 194481MB <Maxtor 6Y200M0> [395136/16/63] at ata3-master UDMA100 GEOM: create disk ar0 dp=0xc5f3b1e0 ar0: 388961MB <ATA RAID0 array> [49585/255/63] status: READY subdisks: disk0 READY on ad4 at ata2-master disk1 READY on ad6 at ata3-master They are in a RAID0 array created using the builtin software RAID in ata. Is this a hardware issue? I don't have much spare SATA equipment to swap around for testing purposes. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755
