[AMD Official Use Only - AMD Internal Distribution Only] Hi,
My "Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)" device stopped working on recent kernel builds (fails to show up in 'ifconfig' or to get an IP address). I bisected the failure down to the following commit: commit a0285236ab93fdfdd1008afaa04561d142d6c276 (HEAD, refs/bisect/bad) Author: Jedrzej Jagielski <[email protected]> Date: Thu Apr 10 14:59:56 2025 +0200 ixgbe: add initial devlink support Add an initial support for devlink interface to ixgbe driver. Similarly to i40e driver the implementation doesn't enable devlink to manage device-wide configuration. Devlink instance is created for each physical function of PCIe device. Create separate directory for devlink related ixgbe files and use naming scheme similar to the one used in the ice driver. Add a stub for Documentation, to be extended by further patches. Change struct ixgbe_adapter allocation to be done by devlink (Przemek), as suggested by Jiri.

Starting with this patch, it fails to do so. I'm not familiar with how to debug this particular device, so please let me know what other information would be of assistance. lspci -vv information (on a working build): c2:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01) Subsystem: ASRock Incorporation Ethernet Controller 10G X550T Physical Slot: 0-1 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 77 IOMMU group: 12 Region 0: Memory at 18020800000 (64-bit, prefetchable) [size=4M] Region 4: Memory at 18020c04000 (64-bit, prefetchable) [size=16K] Expansion ROM at b6000000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: ixgbe Kernel modules: ixgbe Thanks --David Kaplan
