Ok, so this is likely fixed by 3741bbb207f7b9e92ad3b878a30ccd1ddcdb8ac8 , which is in 4.8, so I guess that's coming with next kernel version upgrade. It seems the same issue on upstream kernel-v4.10.0 with s39x arch.

*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are 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 25 has now been rebased to 4.10.9-100.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 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. *********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 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. |
