Works for me. x86_64 work station, Plasma DE, nVidia card (GK107) /nouveau.

Since this is still implicitly testing regressions vs. 4.11.11, it's still getting -1 from me for breaking suspend functionality on my E531, and failing to boot in a VM when Plymouth is enabled (and also giving other related QXL errors later if a graphical boot is disabled). Relevant bugs are #1480602 (suspend) and #1462381 (VM boot failure).

No, this is no longer testing regressions against 4.11. 4.12.5 is the current stable F26 kernel. I understand QXL is broken, we fixed one issue and that opened another. The fact is, upstream QXL seems too busy to care at the moment. I want to get it fixed myself, but regardless of karma, I will push a security update that can impact multiple users, regardless of QXL. There are plenty of workarounds for QXL at the moment. Please don't give any more down karma for QXL, it will be ignored. I hope to find a fix for QXL soon.

Reversing karma, per @jforbes's comment. Regardless of the merits or lack thereof of karma in this case, I had it in my head that both this update and the F25 update had superseded 4.12.5, but that was only true of F25.

Having said that, and not wanting to sound like a petulant child saying "I'll take my toys and go home", recent kernels seem to break more existing functionality than previously in my experience. I realize Fedora is a bleeding-edge distro, but there's still a line where bad user experience is being crossed. Colour me frustrated.

Thanks, and I completely understand your frustration. The 4.12 series in particular had a couple of speed bumps, though most of them are for the longer term good. We have been tracking them down as we can, and QXL is pretty high on that list now, unfortunately there were some more critical issues we had to address first.

My USB wi-fi adapter still does not work with this kernel, just as it did not work with the earlier 4.12.5 kernel. Rebooting back to a 4.11.x kernel and it works fine.

Do you have a bug number? Still is not a regression from the current kernel (4.12.5 is stable)

Can this update be moved to testing?

This update has been pushed to testing.

still not in updates-testing for me

please look into bug 1482649


the 4.12 kernels are causing havoc with the Logitech Unified Reciever. I tried reporting upstream but my attempts were thwarted by the email server.

Can you please stop this bullshit! Take your tests to rawhide!

Works fine on Lenovo R61 with nouveau driver.

karma: +1 critpath: +1

The regressions from 4.11.11 are still unfixed: https://bugzilla.redhat.com/show_bug.cgi?id=1482649 https://bugzilla.redhat.com/show_bug.cgi?id=1483272 Works fine otherwise.

Works great on Lenovo X220! LGTM! =)

This update has been pushed to stable.

Unfortunately BZ #1484587 still occurs with this kernel.

1480829 RT3573 does not work on 4.12.x but works OK on 4.11.x
