works for me - first kernel with spectre-v1-migitation - /sys/devices/system/cpu/vulnerabilities/meltdown: Mitigation: PTI, /sys/devices/system/cpu/vulnerabilities/spectre_v1: Mitigation: __user pointer sanitization, /sys/devices/system/cpu/vulnerabilities/spectre_v2: Mitigation: Full generic retpoline

This update has been submitted for batched by jforbes.

wfm: desktop 16GB Intel i7-3770 CPU, laptop 16GB Intel i7-3610QM CPU, laptop 8GB Intel i5-2520M CPU Lenovo T420 - all using the Mate Desktop Environment ( kernel progression passed on all 3 - performance test took too a very long time for the T420, roughly 2 hours)

works fine

@jforbes: Did you intentionally submit this for batched instead of stable?

I did, there has been a bit of talk in FESCo and on the lists lately about utilizing batch more, so I figured I would give it a try. While there are improvements to Spectre mitigations here, they are not huge over what we had (we were carrying older v1 patches before that didn't report under the new structure, but were there). I suppose with the rebase timing though, it is best to get this one out.

The backtrace does not contain enough meaningful function frames to be reported. It is annoying but it does not necessary signalize a problem with your computer. ABRT will not allow you to create a report in a bug tracking system but you can contact kernel maintainers via e-mail.

Not good. This kernel really has a problem with Thunderbolt networking. It really screws up ssh and also other networking functionality, test case on a Precision 5520 with TB16 and other thunderbolt based NICs. See bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1537597

Automated Test Results

Test results and gating status may sometimes conflict as the gating status is retrieved periodically by Bodhi's backend server, while the test results presented here are retrieved upon page load. If your update is marked as gated while all the tests show green/passed, the next check of gating status should open the gate.
