Abstract: PC SERVER 704 HANGS WITH PCI BRIDGE TO BRIDGE ADAPTERS
SYMPTOM:
The PC Server 704 Models 8650-4BW, 7AX, and 4M0 trap or hang
under heavy workload with PCI Bridge to Bridge Adapters
installed.
PROBLEM ISOLATION AIDS:
The IBM Triple LanStreamer adapter (Option p/n 25H6304, FRU p/n
25H6305) and the Adaptec 3940W and 3940UW are examples of PCI
bridge to bridge adapters.
Diagnostics run without error.
FIX:
Remove any bridge adapters as they are NOT supported in the
models 8650-4BW, 7AX, and 4M0.
Note: PCI bridge to bridge adapters are supported in models
8650-5M0 and 8650-6MM. Refer to the following PC Server
