https://bugzilla.kernel.org/show_bug.cgi?id=74751 --- Comment #23 from Tasev Nikola --- Hi I try again different value for /sys/power/pm_test with the 3.15-rc7 kernel and i notice that with devices selected for /sys/power/pm_test it took long time to resume (12-15 seconds). Looking into dmesg i can see GPU lockup and uvd errors (at 363.74 line). I don't no if this is related to my resume problem. Dmesg is attached. -- You are receiving this mail because: You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=74751 --- Comment #22 from Tasev Nikola --- Hi Daniel, I didn't notice your last reply until today when i was testing the 3.15-rc6 kernel to report that is still not working. cat /sys/power/pm_test give me : [none] core processors platform devices freezer So i echo the different mode to /sys/power/pm_test one by one and then do pm-suspend every time but i could not reproduce the bug, the computer resume normaly after 3-4 seconds. If you need the dmesg after every different suspend resume i can send it to you, just tell me. Just for info, i also test the rc6 kernel with reverting the patch in comment 14 and it works ok after resume. -- You are receiving this mail because: You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=74751 --- Comment #21 from Daniel Vetter --- Ok, the offending commit is actually 177cf92de4aa97ec1435987e91696ed8b5023130, at least that one matches the diff of your change. It references the other commit, but that's not the commit itself. For debugging it might be useful to do the suspend partially. You can disable certain parts of suspend (it will immediately resume if you do this) # echo > /sys/power/pm_test See # cat /sys/power/pm_test for a list of all possible values. If you manage to reproduce the bug with this please attach the drm.debug=0xe dmesg. -- You are receiving this mail because: You are watching the assignee of the bug.

Hi,
Here is the patch from the commit that i found with git bisect.
It's a copy paste from gitk for the commit

}
I just changed the break in the code like before the patch and after
recompiling
the 3.15-rc2 the suspend resume work again.
But like i said i'm just an average user so sorry if i did something wrong.

https://bugzilla.kernel.org/show_bug.cgi?id=74751 --- Comment #13 from Daniel Vetter --- Now I'm even more confused, since 25f397a429dfa is a lot more than a one-line patch. And it _really_ is included in 3.14 already, so git bisect can't possible list that one as the offending commit for a post-3.14 regression, the tool doesn't work like that. Can you please double-check the sha1 and perhaps cite the full commit message + patch to make sure we're talking about the same? -- You are receiving this mail because: You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=74751 Niko Montonen changed: What|Removed |Added CC||montonen.niko at gmail.com --- Comment #10 from Niko Montonen --- I have a Lenovo ThinkPad Edge E325 with the upgraded version of Tasev's APU, the E450, with the HD6320 Wrestler graphics chipset, and I'm suffering from an issue that would appear to be the same as this. I'm currently running 3.14.1 on the machine, and it works just fine, but 3.15-rc1 and 3.15-rc3 both fail to resume from suspend (I haven't tested rc2). The machine hangs completely (network interfaces do not resume etc.), so I'm unable to get dmesg after suspend. I feel it's worth noting that the machine also completely ignores the lid closing with 3.15-rc3, and I believe there are lots of ACPI changes in 3.15, which would explain a lot. Are there notes somewhere on how to get some useful debug info for situations like this? -- You are receiving this mail because: You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=74751 --- Comment #6 from Tasev Nikola --- Hi Daniel, First, sorry if i confuse you , i'm just an averrage user. But yes this is really the first bad commit git bisect found. I saw that it is just one line simple patch but it probably masked another problem elsewhere because the break in the patch is just before the dpms screen code. And yes changing the break 3 lines above like before the patch and recompiling the kernel fixes the problem for now. I dont know from where could come the problem. And yes, all the kernels before the 3.15-rc1 work without a problem. With the broken 3.15-rc2 kernel (non patched), my computer frooze immediately after resume. I only have a black screen, i can't log into console and i must shutdown the computer pressing the power button 10 sec. I attached the dmesg before suspend/resume. For the working 3.15-rc2 with the patch, I attached the dmesg with drm.debug=0xe after suspend/resume. -- You are receiving this mail because: You are watching the assignee of the bug.
