dmesg
It was tested with latest linux-2.6 git and drm-linux. To make clean test i
used test_suspend=mem with acpi_sleep options (s3_bios and/or s3_mode) and
without acpi_sleep. Any acpi_sleep option will make my PC freeze. Without
acpi_sleep it will resume but with black screen and i can access it with ssh.
Disabling kms will resume with black console but Xorg will enable video.
After resume dmesg has two traces, memory corruption and warn_slowpath_common:
