*********** 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 20 kernel bugs. Fedora 20 has now been rebased to 3.17.2-200.fc20. 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 21, and are still experiencing this issue, please change the version to Fedora 21. If you experience different issues, please open a new bug report for those.
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in over 3 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
This bug still exists on latest kernels(4.0 and 4.1). It seems that it's a harddisk firmware bug. While bug similar to https://bugzilla.redhat.com/show_bug.cgi?id=907193 but for other harddisk, I prepare patch and test it on my HP Microserver G7 N54L( harddisk comes with server). Patch already sent to ML: https://lkml.org/lkml/2015/7/1/235
