Hi after test this kernel commit and send some cold reboots to my GLK i noticed that i got some relevant kernel messages kern :emerg : [Sun Dec 4 14:33:10 2016] mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: a600000000020408 kern :emerg : [Sun Dec 4 14:33:10 2016] mce: [Hardware Error]: TSC 0 ADDR fef4c9a0 kern :emerg : [Sun Dec 4 14:33:10 2016] mce: [Hardware Error]: PROCESSOR 0:706a0 TIME 0 SOCKET 0 APIC 0 microcode 1c kern :err : [Sun Dec 4 14:33:10 2016] ACPI Error: Invalid type (RegionField) for target of Scope operator [SSP2] (Cannot override) (20170303/dswload-273) kern :err : [Sun Dec 4 14:33:10 2016] ACPI Exception: AE_AML_OPERAND_TYPE, During name lookup/catalog (20170303/psobject-241) kern :err : [Sun Dec 4 14:33:10 2016] ACPI Exception: AE_AML_OPERAND_TYPE, (SSDT: RVPRtd3) while loading table (20170303/tbxfload-228) kern :err : [Sun Dec 4 14:33:10 2016] ACPI Error: 1 table load failures, 11 successful (20170303/tbxfload-246) kern :err : [Sun Dec 4 14:33:19 2016] uvesafb: Getting VBE info block failed (eax=0x4f00, err=1) kern :err : [Sun Dec 4 14:33:19 2016] uvesafb: vbe_init() failed with -22 kern :err : [Sun Dec 4 14:33:19 2016] atkbd serio0: Failed to deactivate keyboard on isa0060/serio0 kern :err : [Sun Dec 4 14:33:20 2016] atkbd serio0: Failed to enable keyboard on isa0060/serio0 please see the dmesg.log attached i am not sure if this is the same failure for this bug, i will be waiting for a response if i should to create another bug for this or not. BTW, i tested with latest drm-intel and it was the same failure commit bf26e1dbbba24a7697559f1131d4be99747b7646 Author: Martin Peres <<a href="mailto:martin.peres@linux.intel.com">martin.peres@linux.intel.com</a>> AuthorDate: Tue Jun 27 16:59:42 2017 +0300 Commit: Martin Peres <<a href="mailto:martin.peres@linux.intel.com">martin.peres@linux.intel.com</a>> CommitDate: Tue Jun 27 16:59:42 2017 +0300 drm-tip: 2017y-06m-27d-13h-59m-07s UTC integration manifest</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
