Description Mantas Mikulėnas 2014-06-02 07:28:49 UTC 
With 3.15-rc* kernels (including -rc8 built today), hibernation (suspend to disk) doesn't work properly; the system hangs for ~10 seconds and I get a "GPU lockup" message before it continues. The same happens both when hibernating, and when resuming from hibernation. (Suspend-to-RAM, however, works perfectly.) In the last few attempts, during resume it recovered from the lockup, but remained unstable afterwards (see second "GPU softreset" log at the bottom).

The same happens both with Xorg running, and without.

Computer: ASUS K52JT.206 laptop, using UEFI.

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Robson CE [Radeon HD 6370M/7370M] [1002:68e4]

Same problem here (mobility radeon 4550, kernel 3.14.14-gentoo)
Comment 2 Alex Deucher 2014-08-14 13:22:47 UTC 
Is this a regression?  If so, can you bisect?

I am sorry, but I don't think I understand you. What do you mean by "regression"? What am I trying to bisect?

Did it used to work previously?  If so what kernel?  If you know what kernel used to work, you can use git to bisect the changes and identify what change broke it.

Previously, in kernel 3.12.21-r1-gentoo, I had the same problem (the screen is sometimes messy after hibernation, and the same "fence wait failed" error in syslog). Before that, I ran deblobbed kernels 3.8.13-gentoo and 3.4.9-gentoo, and there were also problems with the screen, but a bit different. The screen just became black (sometimes it happened after hibernation, sometimes just during the normal work), but the mouse pointer was there, and the error in syslog was different: it started with "kernel BUG" at some location. I don't have the syslog from 3.8.13, but in 3.4.9 it was at mm/slub.c:3474 .

On my system, both problems (the one I have now and the one I had previously) happen rather irregularly.
Comment 6 Rostislav Devyatov 2014-08-18 15:21:16 UTC 
Also, after a "normal" wake-up from hibernate, when the screen does not get distorted, I see the following message in dmesg:

[drm:rv770_dpm_set_power_state] *ERROR* rv770_set_sw_state failed

Narrowed it down to the UVD merge for 3.10 (f18353eee757).

ec5891fbe1b0 ("drm/radeon: UVD bringup v8") was the first commit with the "fence wait failed" errors:

Seven commits in between [f2ba57b5eab8, ef0e6e657cfe] were also bad, but with a different error message:

Comment 8 Barto 2014-09-22 08:48:03 UTC 
I have the same problem with my radeon HD4650 PCie ( I use the radeon driver ), with dpm actived,

the hibernation doesn't work, it fails with an error message in the console related to my radeon HD4650 "fence ring error",

then at reboot fsck starts, which reveals that the hibernation has failed
