BACKGROUND: We've implemented a disk drive testing system under 2.6 using LibATA to access the ATA devices. During testing, we attach additional "test" drives to the system and perform reads and writes to these drives. The system drive is not part of the test environment. During testing we expect to see errors reported (read, write and time-out) from the "test" drives. When a SCSI disks report errors, the SCSI handlers perform as expected, reporting the error and recovering. When ATA drives report errors, only read errors recover and we are able to capture the error. Write and time-out errors hang the system.
Hardware tested: Promise Ultra133 TX2 (PDC20269 chip; pata_pdc2027x driver) Kernel versions tested: 2.6.11 2.6.14 rc2 2.6.15 rc5RECREATING THE PROBLEM: In our situation, we see the write and time-out failures when we screen drives beyond their commercial temperature limits for military applications using a custom application to read and write to the "test" drives. Rather than having to have a drive in a special temperature environment, the easiest way to simulate the failures is to unplug power to a test drive while it is under test. The resulting errors and time-outs will hang the system. Under this scenario, any type of read or write to the "test" drive will fail the same as with our application. I've attached copies of the system messages and startup-log to give further details into the hangs.
