I recently tried the latest 3.17.0-rc1. The computer will suspend and resume correctly, but I am still having:
1) corrupted graphics, mainly fonts, but also shapes
2) many repeated warnings in the dmesg log.

I don't know if I should keep posting here or not. I just built 3.17-rc4. Suspend and resume still works, but I still get the modeset message in the logs. Is this because my install uses a modeset of -1?

Sorry we've neglected this bug a bit. Thanks for the updates.

Please attach full dmesg from boot with the drm.debug=0xe module parameter set.

I think I got it. I added drm.debug=0xe in the /etc/modules file and rebooted. The dmesg is attached.

Created attachment 149701 [details]
Dmesg at boot 3.17.0-rc4

Still there in rc5. Did I do the debug correctly?

I'm afraid it didn't go through. It may be easiest to edit the kernel command line at boot loader. For example, if you use grub, hit 'e' when the kernel is selected, and add drm.debug=0xe at the end of the linux command line. Hit F10 to boot (IIRC).

Alternatively, you can use /etc/modprobe.d/somefile.conf and add the line:

options drm debug=0xe

there.

I just did it and created the dmesg text, but it only starts at 31 milliseconds. I do nto know why it does not give the complete log. I attached what I got, anyway, in case it is helpful.

debug dmesg 3.17.0rc5

Unfortunately it's not too helpful as we can't see the first errors; usually the later errors are a byproduct of the first one. Please try to get the full dmesg. Maybe add log_buf_len=4M kernel parameter to set the kernel log size to 4 mb. Or more.

the new one starts at 0. Hope this helps.

Thanks!

3.17-rc5 debug messages (this time from 0)

SDVO state tracking fails are for Daniel.

Anything new on this? I have not tried to build another kernel since this 3.17-rc5 as there has been no updates. I will build and test if a fix can be tried.

Keith

Updating priority to reflect reality. Please try later kernels.

Long time no updates, closing.

If the problem persists with latest kernels, please file a bug at the freedesktop.org bugzilla [1], referencing this bug. Thank you.
