Kernel version 3.19.5 log + log data before resume/crash

You can clearly see the moment of hibernation based on the break in the
relative monotonic timestamp list. Please pay attention especially to the
failed ring 1, 2, and 3 tests by the drm device driver:
[21546.321630] xxxxx kernel: [drm:cik_ring_test [radeon]] *ERROR* radeon: ring
1 test failed (scratch(0x3010C)=0xCAFEDEAD)
[21546.473738] xxxxx kernel: [drm:cik_ring_test [radeon]] *ERROR* radeon: ring
2 test failed (scratch(0x3010C)=0xCAFEDEAD)
[21546.588708] xxxxx kernel: [drm:cik_sdma_ring_test [radeon]] *ERROR* radeon:
ring 3 test failed (0xCAFEDEAD)

Please also note:
[    3.662536] xxxxx kernel: ACPI Error: [\_SB_.ALIB] Namespace lookup failure,
AE_NOT_FOUND (20141107/psargs-359)
[    3.662639] xxxxx kernel: ACPI Error: Method parse/execution failed
[\_SB_.PCI0.VGA_.ATC0] (Node ffff88042f0c9a78), AE_NOT_FOUND
(20141107/psparse-536)
[    3.662709] xxxxx kernel: ACPI Error: Method parse/execution failed
[\_SB_.PCI0.VGA_.ATCS] (Node ffff88042f0c9a50), AE_NOT_FOUND
(20141107/psparse-536)

I am not an expert but this error seems to be linked to the drm device driver.
