H133573 - 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/n25H6304, 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.
