IBM ValuePoint - Hang or trap 000E with 256K write-thru L2 cache
Applicable to: World-Wide
Symptom:
PS/Valuepoint-2 6384/D, 6382/S and 6387/T 433DX (486 33MHz) systems may experience system hang conditions or trap 000E errors with a 256Kb write-thru cache option installed (f/c 5296, option p/n92G7218, FRU p/n92F0398).
Problem Isolation Aid:
Systems with the 256Kb write-thru cache option installed may hang using any operating system. Trap 000E errors may be experienced in systems using OS/2 2.x.
PS/Valuepoint advanced diagnostics run without errors. Remove the 256Kb write-thru cache option from the system and attempt to recreate the failure. If the error can be recreated with the cache module removed, this tip does not apply. Utilize normal problem determination procedures to isolate the failing FRU.
If the failure cannot be recreated with the 256Kb write-thru cache option removed, this tip does apply. Proceed to the "fix" section of this tip. Systems with the 128Kb write-thru cache option are not affected. Systems with either a 128Kb or 256Kb write-back cache option are also not affected.
Replacement of either the system board and/or the 256Kb write-thru cache module will not resolve this failure.
Fix:
If the failure cannot be recreated with the 256Kb cache module removed, replace the 256Kb write-thru cache module with the 256Kb write-back cache, FRU p/n92F0400. The 256Kb write-thru cache module fru number (p/n92F0398) is being substituted to the 256Kb write-back cache FRU number (p/n92F0400) in the Mechanicsburg parts system. There is no performance degradation as a result of this change.
Note:
433DX systems with type 1 system boards must have Flash BIOS level 54A or higher installed before adding the 256Kb write-back cache module.
