FAS2xxx: Missing e0a/e0b/e0M/e0P and Invalid PCIe Device
Source scope and behavior
The source lists FAS25xx, FAS22xx and FAS2750 with the Intel82580 quad-Gigabit Ethernet controller. It describes a reboot without a panic, earlier igb interface-hang events, or a node that stays up but stops responding through e0a/e0b/e0M. Some boots report missing interfaces or hardware-initialization failure.

slot 0: Interconnect HBA: Mellanox IB MT25204Case diagnosis and action
The source identifies an onboard Intel82580 hardware failure and prescribes motherboard replacement. In practice, confirm the exact failed FRU and supported controller/board replacement procedure with the vendor; “motherboard” and a field-replaceable controller assembly are not automatically interchangeable repair instructions across the listed systems.
The matching official English FAS2xxx case and CHW-219 symptom reference support comparison of the error pattern. CHW-219’s public page specifically names FAS2500; do not use it alone to extend a fix to every FAS model in the broader source list. Full gated solution details were not read.
