*********** 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 23 kernel bugs. Fedora 23 has now been rebased to 4.7.4-100.fc23. 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 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25. If you experience different issues, please open a new bug report for those. Created attachment 1206962 [details]
Output of dmesg with kernel 4.7.5-200.fc24.x86_64
The problem still exists with kernel 4.7.5-200.fc24.x86_64.
I have attached the output of dmesg containing the backtrace with this kernel.
This is warning about a BIOS bug and the change to a WARN_ON_ONCE was made deliberately https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f3c78f8515dd4cb9e26040ebb54cf589d21137ee . A real fix would need to come from the BIOS so there isn't much the kernel can do. |
