03:01.0 PCI bridge: IBM PCI-X to PCI-X Bridge (rev 02) (prog-if 00 [Normal decode])
Flags: bus master, 66Mhz, medium devsel, latency 64
Bus: primary=03, secondary=04, subordinate=04, sec-latency=64
I/O behind bridge: 00003000-00003fff
Memory behind bridge: f7e00000-f7efffff
Prefetchable memory behind bridge: 00000000f1100000-00000000f11fffff
Capabilities: [80] PCI-X bridge device
Capabilities: [90] Power Management version 2
Is that the same bridge chip? This comes from a DL380 g3 with hot-swap cage.
