Xorg.0.log with error messages
Bug description:
Graphics display frozen (mouse pointer still moves) after resume from
hibernation. Xorg.0.log filled with:
(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or
even a frozen display: Invalid argument.
This is a regression, hiberate worked fine up to Linux kernel 3.11.
System environment:
-- chipset: GM45
-- system architecture: i686
-- xf86-video-intel: 2.19.0
-- xserver: 1.12.4
-- mesa: 2.1 Mesa 8.0.5
-- libdrm: 2.4.40
-- kernel: 3.12.23, 3.14.16, 3.16
-- Linux distribution: Debian Wheezy
-- Machine or mobo model: Lenovo Thinkpad X200 Tablet
-- Display connector: Integrated panel
Reproducing steps:
* Boot system
* On login screen (I use lightdm, but it's also reproducible from within an
Xfce session), click "Hibernate"
* Wait a few minutes (10 min always seems to be enough, immediate resume
sometimes doesn't show the problem)
* Power on
* Wait for resume from hibernation
* Old screen shown again, but cursor not flashing and no interaction possible
* Switch to VT1 using Ctrl-Alt-F1
* Inspect /var/log/Xorg.0.log
Additional info:
git-bisect showed that commit 17fec8a08698bcab98788e1e89f5b8e7502ababd
(drm/i915: Use Graphics Base of Stolen Memory on all gen3+) from
<a href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git">https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git</a>
causes the problem. Reverting to the previous commit
f63a484c2f606b8267eb4d1dbfce5d1d3416e0bb fixes the problem.</pre>
