Dear all, After I reverted BIOS back to default setting, I found some following error messages related to ACPI:
[ 0.847234] ACPI: Thermal Zone [THM] (25 C) [ 0.847347] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECAV] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359) [ 0.847605] ACPI Error: Method parse/execution failed [\_TZ.TZ00._TMP] (Node ffff987b7d51dac8), AE_NOT_FOUND (20160831/psparse-543) [ 0.848038] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECAV] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359) [ 0.848240] ACPI Error: Method parse/execution failed [\_TZ.TZ00._TMP] (Node ffff987b7d51dac8), AE_NOT_FOUND (20160831/psparse-543) [ 0.848524] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECAV] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359) [ 0.848725] ACPI Error: Method parse/execution failed [\_TZ.TZ01._TMP] (Node ffff987b7d51de38), AE_NOT_FOUND (20160831/psparse-543) [ 0.848998] ACPI Error: [\_SB_.PCI0.LPCB.H_EC.ECAV] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359) [ 0.849198] ACPI Error: Method parse/execution failed [\_TZ.TZ01._TMP] (Node ffff987b7d51de38), AE_NOT_FOUND (20160831/psparse-543) How to fix this problem?
