Previously, using NIC bonding could have led to an unexpected termination of "tuned". With this update, the network device type determination has been fixed by handling more error conditions so that the aforementioned bug no longer occurs.

Easy to fix. Patch committed upstream. http://git.fedorahosted.org/git/?p=tuned.git;a=commit;h=ba38290 Any updates on this issue? I have to report that I have pulled tuned from the git repository and built the RPM and installed it on an RHEL6.1 system and it still fails with the errors as originally reported:

Please change the line except (IOError, AttributeError): to except (IOError, AttributeError, OSError): in the patch. Tested and confirmed that it works now! Thanks! Frank Swasey

Description of problem: tuned cannot start; seems to be related to NIC bonding Version-Release number of selected component (if applicable): tuned-0.2.19-4.el6.noarch How reproducible: Every time Steps to Reproduce: 1. /sbin/service tuned start 2. /sbin/service tuned status Actual results: "tuned dead but subsys locked" Expected results: Should see that tuned is running.
