IBM PC Server/IBM PS/2 - DMA timeout error (TRAP0002)
Applicable to: World-Wide
Symptom:
OS/2 trap 0002 (DMA Timeout) error occurs on a PS/2 system during operation. Other operating systems will produce different DMA timeout failure symptoms, such as "Panic" hangs, NMI errors, etc
Problem Isolation Aids:
The system hardware diagnostics complete without error. The PS/2 has a DMA controlled arbitrable parallel port. (All IML systems have arbitrable serial and parallel ports). The parallel port DMA arbitration level is at a setting other than "disable".
Fix:
If the failure occurs only when a certain adapter is being utilised. The problem may be circumvented by changing the adapter arbitration level to a setting other than "0".
If problems are still encountered, the parallel port DMA arbitration level, should be set to "disabled". These changes are accomplished by using the "Change Configuration" option on the system partition or reference diskette.
This problem is currently under investigation by engineering. Additional information will be communicated via the Retain tip when available.
If problems are still encountered after disabling the parallel port DMA arbitration level, normal problem determination should be performed.
