Description Guang Yang 2011-10-18 20:12:06 UTC

System Environment:
--------------------------
Platform:        IvyBridge
Kernel: (ivb-3-pipe)344f5205ecf58b0c56f7d6439621fa5467e9881e

Bug detailed description:
-------------------------
First we start the system with 3 displays active, then we do "echo disk>/sys/power/state" for s4,the system fail to hibernate,it stuck 
with power on and we can't ssh to login.

Comment 1 Guang Yang 2011-10-19 01:28:16 UTC

This bug only occur with the 3-pipe kernel.

Comment 2 Guang Yang 2011-10-19 02:48:50 UTC

I have test S4 with another kernel,the system may fail to hibernate after s4 sometimes,not all the time.

System Environment:
--------------------------
Platform:        IvyBridge

Comment 3 Eugeni Dodonov 2011-10-19 04:59:08 UTC

Jesse - it looks suspiciously similar to other S4-related issues. I think we could try to workaround this by disabling KMS during suspend.

@Yangguang - does the issues happens with 'nomodeset' kernel parameter?

I have try to start the system on two different kernels with 'nomodeset' kernel parameter,the issues still happens .

Comment 5 Gordon Jin 2011-11-01 01:06:23 UTC

I'm increasing the priority to high, since the code has been merged into drm-intel-next.

Comment 6 Gordon Jin 2011-12-15 22:39:59 UTC

Jesse/Eugeni, can you reproduce this?

Could you try with the http://cgit.freedesktop.org/~eugeni/kernel/log/?h=ivb-suspend tree please?

I have try this patch with drm-intel-next,it can work well.

Comment 9 Eugeni Dodonov 2012-02-16 10:03:49 UTC

The patch was included in development trees and backported to 3.2.6 kernel, so closing as fixed.

If it still happens, please, let me know!

Comment 10 Gordon Jin 2012-02-16 16:18:44 UTC

Good to know. Since it's in 3.2.x, add the release tracker.

Comment 11 Elizabeth 2017-10-06 14:51:41 UTC

Closing old verified.
