The bug is still there with kernel 3.14-rc6 - the display doesn't get
enabled on resume. But now the logs (attached) don't contain any obvious
failures.

Title:
ATI Resume from Suspend leads into black screen
Taking a tip from https://bugs.freedesktop.org/show_bug.cgi?id=58382, I
tried suspending using pm-suspend --quirk-test --quirk-s3-mode and
this works for me too. Using this, the display *does* get re-enabled on
resume.

I just tried 3.11-rc3, with the important difference that I kept both
cards active when suspending.
When resuming, the backlight now came on for a second but the screen
then turned dark again. Looking at the logs, the failure now seems less
catastrophic than before.
Could it be that if I disable

Including previously missing REDWOOD_smc.bin changes the log slightly.

I applied the patch to kernel 3.10.3 and it made no discernible
difference. But that patch is just supposed to fix backlight problems,
right? I don't think my display gets re-enabled at all. I don't see
anything when shining on it with a bright flashlight after resuming.

Bug is still present in kernel 3.8. After resuming, I get
Feb 21 14:32:18 mars kernel: [ 148.029820] [drm:atom_op_jump] *ERROR* atombios
stuck in loop for more than 5secs aborting
Feb 21 14:32:18 mars kernel: [ 148.029836] [drm:atom_execute_table_locked]
*ERROR* atombios stuck executing CC40
Resume still doesn't work with kernel 3.8-rc2. However, I now get a hard
lockup on resume. Log attached.

Correction: it's *not* a hard lockup - the laptop still responds to
ping. It may just be that the keyboard is not working after resume (or
even that I mistyped something when trying to reboot it by typing
blind).
