After enter to S3 or S4, system can't resume again via pressing power button

Reproduce step:

Comment 1 Chris Wilson 2013-08-04 08:20:08 UTC
There is no information here... Nothing at all to suggest that this is a i915 issue.

Attach the dmesg. Check whether the system can suspend and resume without ever loading i915.
Comment 2 Daniel Vetter 2013-08-04 16:59:42 UTC
Jesse is the Batrail owner.
Comment 3 kobeqin 2013-08-05 10:26:06 UTC
We try to add nomodeset, but enter to system and lsmod, i915 still listed. rmmod i915 and this bug still can duplicate.
Comment 4 Chris Wilson 2013-08-05 12:48:45 UTC
Since i915.ko will not load on Baytrail-M if nomodeset is set, I think something went wrong in testing.

Adding nomodeset to grub, i915 is listed by lsmod, but used by "0", does it mean that i915 doesn't load? And S3/S4 still can't resume after adding nomodeset
Comment 6 Jani Nikula 2013-08-08 13:23:02 UTC
Please attach the dmesg.

Jani, after entering to S3 or S4, system can't resume anymore. We try to use mincom to print,but it can't work on baytrail-M, do you have any instruction?
Comment 8 kobeqin 2013-08-17 15:03:11 UTC
Jani,due to long time no response, I have written an email to you and have to change the status to NEW until we can carry out a solution to get dmesg or a log from COM port.
Comment 9 Jani Nikula 2013-08-19 07:10:26 UTC
First things first, please let's make sure you're not loading i915. What kernel parameters are you using? What values do you have for CONFIG_DRM_I915_KMS and CONFIG_VGA_CONSOLE kernel config options?

i915.modeset=0 should trump all other options, and should prevent i915 from loading.

If you can still reproduce the bug *without* i915 loaded, it's NOTOURBUG.
Comment 10 Jani Nikula 2013-08-19 07:35:02 UTC
Hmm, might be you need to give a bogus parameter to i915 to prevent it from loading, e.g. i915.foobar

Disregard that, supposedly this doesn't work anymore since 3.11.

We have added i915.modeset=0, S3/S4 still can't resume.
Comment 13 Jani Nikula 2013-08-20 06:26:30 UTC
NOTOURBUG. I'm afraid I don't know who the owner would be, though.
Comment 14 kobeqin 2013-09-09 03:07:00 UTC
As Jani said, it's not our bug after we verified w/o i915.
Comment 15 Elizabeth 2017-10-06 14:44:24 UTC
Closing old verified.
