Bug Description
== Comment: #17 - Guilherme Guaglianoni Piccoli - 2016-07-27 18:49:08 ==
Temperature and fan information from hardware are normally available to userspace through hwmon sysfs abstraction. In case of be2net driver, all PCI devices "managed" by this driver have hwmon entries, which are filled in a delayed workqueue on driver, every 64 seconds.
The issue we're seeing is that the hardware temperature queries to devices' fw are performed only in devices which interface is up - so, we end up having messages like below when using the "sensors" tool (from lm-sensors), for example:
be2net-pci-50100
Adapter: PCI adapter
ERROR: Can't get value of subfeature temp1_input: I/O error
temp1: N/A
The following upstream commit addresses this issue:
d3480615cf ("be2net: perform temperature query in adapter regardless of its interface state")
[https:/
We would like Canonical to merge this commit in the Xenial kernel.
Thanks in advance,
Guilherme
