Description Mauro Carvalho Chehab 2013-06-19 18:00:18 UTC
Description of problem:

While this motherboard have lots of sensors, those aren't currently available on Fedora 18, as the Kernel driver is recent.

Version-Release number of selected component (if applicable):

Kernel-3.9.6-200

How reproducible:

Always.

Actual results:

Only the CPU sensors are available. It misses Fan, voltage and motherboard sensors.

Expected results:

All sensors should be visible by the userspace tools.

Please don't backport those.  F18 will get 3.10 in a relatively short period of time.

Comment 2 Josh Boyer 2013-07-01 17:38:19 UTC
This is fixed in the latest F18 update.
