Same problem here, but different laptop (HP EliteBook 850 G3). Happens with several kernel versions, but currently running 4.8.4-200.fc24.x86_64. Whenever this message happens, the screen does blank as well, making this very annoying.

Then reboot and see how things go. Regards, Hans I'd say you are correct in that 4.8.6 fixes this for me. Although I've only been running with this kernel for a day and a half now (I only am in this office for 5 days every 2 weeks, so did not have more opportunity to test), but I certainly do notice an improvement. Thanks! kernel-4.8.8-200.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-3548475bca kernel-4.8.8-200.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report. The same error is occurring here with Lenovo T460s notebook, Fedora 27, Kernel 4.15.16-300.fc27.x86_64 I had to force restart the notebook. Kindly advise, Pierre |
