Upgraded from 6.8.2 to 6.9.2 and my 10gb nic no longer works. In the log ixgbe is spamming errors:
Apr 13 01:56:35 unraidserver kernel: ixgbe 0000:07:00.0: Warning firmware error detected FWSM: 0x00000000 Apr 13 01:56:36 unraidserver kernel: ixgbe 0000:07:00.1: Warning firmware error detected FWSM: 0x00000000
The nic was working prior to the upgrade. It's an Intel X520-T2 but is reported through lspci as an 82599 (which shouldn't matter).
