Title:
Kernel does not report interface speed correctly for Cisco UCS B200 M5
blade
Status in MAAS:
Triaged
Status in linux package in Ubuntu:
Confirmed
Bug description:
MAAS 2.7.1
Ubuntu 18.04.4
When attempting to commission a Cisco UCS B200 M5 blade, the
commissioning finishes (if smartctl-validate is disabled), however on
the machine in question in the Networking tab, it only shows 2 nics,
eth0 and eth1. and shows no storage.
Going to SSH in the middle of commissioning, running lshw shows all 10
NICs, and the disk of the proper size.
This is causing the buckets.yaml for FCE to be inaccurate, and thus
cannot write a bucketsconfig.yaml since the actual devices don't show
up.
This was tried with bionic {ga,hwe,hwe-edge} and focal ga kernels for
commissioning, all have the same behavior.
I was previously hitting this bug
https://bugs.launchpad.net/maas/+bug/1878643 but applied the fix from
comment #10, and am no longer getting any commissioning errors.
