*********** 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 24 kernel bugs.
 
Fedora 24 has now been rebased to 4.7.4-200.fc24.  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 25, and are still experiencing this issue, please change the version to Fedora 25.
 
If you experience different issues, please open a new bug report for those.

Comment 2 g. artim 2016-10-24 18:38:04 UTC
It was fc25, sorry typo. I used on the server edition and noted the dump in the syslog, but no problems I could find running the code. More of an fyi. I'll retest on that machine when 25 is released and reply, Gary

Comment 3 g. artim 2016-10-24 18:42:00 UTC
I just noted the kernel say 24, but I did a 

sudo dnf system-upgrade download --refresh --releasever=25
sudo dnf system-upgrade reboot

maybe the kernel update didnt happen. I'll try a retest.

Comment 6 g. artim 2017-03-07 15:06:34 UTC
Maybe I should just stop reporting these errors since I never seem to get much response. And just get "form response" when the release has matured. gary
