Description Sean Fu 2017-01-24 08:03:13 UTC

Description of problem:
My laptop is DELL E5450. When I used Fedora23, everything is fine. After I upgrade to Fedora24/25, it showed every time that failed to enable SMBus PCI device during the boot. I found kernel modules are loaded,but kernel driver is not in use.



Version-Release number of selected component (if applicable):
The version of kernel is the latest, which is 4.9.4-201.fc25.x86_64

How reproducible:
When I boot the system, it shows every time.


Actual results:
Failed to enable SMBus PCI device (-16)

Expected results:
no warnings

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 25 kernel bugs.

Fedora 25 has now been rebased to 4.10.9-200.fc25.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26.

If you experience different issues, please open a new bug report for those.
