IBM PC330/PC350 - Hangs and Trap 000E errors with 256KB L2 cache
Applicable to: World-Wide
Symptom :
IBM PC 300 Series 6577 and 6587 systems may exhibit intermittent system hangs, Trap 000E errors in OS/2 WARP, and other memory related errors posted by various operating system platforms on systems containing a Level 2 cache module made by UMC for IBM.
Problem Isolation Aids :
UMC cache modules can be identified by the UMC brand logo printed on the modules chips. The barcode label attached to the affected cache modules contains a header code of J1111.
The FRU part number is P/N 07H1150. No other brand of level 2 cache stocked under FRU P/N 07H1150 is affected.
Advanced Diagnostics run without errors.
Remove the 256Kb L2 cache module 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 or application.
If the failure cannot be recreated with the 256Kb cache module removed, this tip does apply. Proceed to the "FIX" section of this tip.
Fix :
The cause of the failure is a buildup of contaminants between the cache module tabs and the contacts on the system board cache socket.
Remove the cache from the socket and reseat the module several times to remove the contaminants and provide a solid connection between the tabs and the contacts. Retest the system.
If the system continues to exhibit the failure after reseating the cache module, replace the cache module FRU P/N 07H1150.
All affected UMC brand cache modules stocked under FRU P/N 07H1150 have been purged from FRU inventory, reworked and restocked with a new barcode number. The FRU part number was not changed.
