Running this on XPS 9550 so far so good.

karma: +1

Have been testing on:

• Thinkpad W541 with nvidia gpu
• i7-4790k with AMD RX 480 and open source amdgpu driver

No issues, all smooth. Thanks,

Boots on T450s, XS35GTV2 and a VM.

works for me on Intel i5-3550 x86_64 with rpmfusion nvidia GTX980 driver and as virtualbox host.

works for me, VM and two phyiscal machines, one of them VMware-Host, Router, Firewall, WLAN-AP..

no regressions noted

WFM, Thinkpad X250

No regressions noted on x86_64 and i686+PAE.

wfm, regression tests all passed: desktop 16GB Intel i7-3770 CPU, laptop 16GB Intel i7-3610QM CPU - took an excessively long time for the performance run, about 106 minutes, - all using the Mate Desktop Environment

Won't power-off for me - from either gnome-shell or 'shutdown -h now' - reboots after around a 3 - 5 second pause. Happens on both:

• Dell XPS 13 9350
• Dell XPS 15 9560

and does not happen with kernel 4.15.17 or older.

Works for me on one AMD server, one Intel desktop with Nvidia proprietary drivers and one Atom laptop. No regressions noted.

• Works for me on Thinkpad X220 and X240
• paxtest still fails running kernel regression test (-1)

Doesn't work with qemu/KVM on a HP xw4400 workstation, a lot of calltrace, only hard shutdown works then ....

No regressions spotted on: * IvyBridge + Radeon HD7670M (suspend on login with lid closed seems gone) * AMD Athlon X2 260 + Radeon R7 240 (now also working on xorg-x11-drv-amdgpu - hello Vulkan!) * Dell Optiplex 780 (E8400)

@gerhardw thanks for testing and reporting that. It looks like that's bz 1566258 and a patch has been submitted upstream with a potential fix, but hasn't been reviewed and accepted yet.

I started a test build with that patch applied, when the build is done can you confirm it fixes the problem?

Works for me (Thinkpad T440s) . Passed default kernel regression test.

@jcline test build at https://koji.fedoraproject.org/koji/taskinfo?taskID=26538797 works well, thnx.

4.16.4 has also been released ... https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.16.4

Works ok on T470.

Working on X1 Carbon 4th Gen and Xeon D1520.
