--- Comment #12 from gitne at excite.co.jp --- Created attachment 175411 --> https://bugzilla.kernel.org/attachment.cgi?id=175411&action=edit 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. -- You are receiving this mail because: You are watching the assignee of the bug.
