The use case I guess is if you want/need to do some TCP dumping from a live image. kernel-4.8.0-0.rc1.git3.1.fc25 has been submitted as an update to Fedora 25. https://bodhi.fedoraproject.org/updates/FEDORA-2016-1784e6a050 kernel-4.8.0-0.rc1.git3.1.fc25 has been pushed to the Fedora 25 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-1784e6a050 After upgrade to latest ernel and upgrade tcpdump package now seems everything is ok. # uname -r;rpm -q tcpdump 4.8.0-0.rc1.git3.1.fc26.x86_64 tcpdump-4.8.0-1.fc26.x86_64 We need the bug open for F25 freeze exception tracking. Discussed during the 2016-08-15 blocker review meeting: [1] The decision to classify this bug as an AcceptedFreezeException was made as the bug seems significant enough to ensure it's fixed on the live images. Help from the kernel team on this one is appreciated. [1] https://meetbot.fedoraproject.org/fedora-blocker-review/2016-08-15/f25-blocker-review.2016-08-15-16.00.txt The patch is in the rawhide and F25. tcpdump works fine with kernel-4.8.0-0.rc1.git3.1.fc25 . kernel-4.8.0-0.rc2.git2.1.fc25 has been submitted as an update to Fedora 25. https://bodhi.fedoraproject.org/updates/FEDORA-2016-0dd1a509c8 Created attachment 1192102 [details]
3 days temperature
Just had a look on 4 temperature sensors data which reading on this laptop.
Despite theoreticall much higher cpu usege by additional %softirq time seems CPU conumption measured as amout of heat generated in CPU is almost the same on kernels 4.5.5 and latest 4.8rc1.
These temperature data shows that kernel 4.5 or 4.8 cpu stats may be wrong.
It is as well possibility that cpu usage on both kernels are somehow broken as well.
Here is raw output of sensors command showing what is possibe tp measureon this laptop.
