On my HP 2510p notebook I get five ACPI errors when the hp-wmi driver attempts to read hddtemp. $ cat /sys/bus/platform/devices/hp-wmi/hddtemp cat: /sys/bus/platform/devices/hp-wmi/hddtemp: Invalid argument In dmesg this results in: ACPI Exception (exoparg2-0445): AE_AML_PACKAGE_LIMIT, Index (000000002) is beyond end of object [20090320] ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.C2FA] (Node ffff88007e042420), AE_AML_PACKAGE_LIMIT ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C2BB.C2D9] (Node ffff88007e040180), AE_AML_PACKAGE_LIMIT ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C2BB.C2D0] (Node ffff88007e01efc0), AE_AML_PACKAGE_LIMIT ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C2BB.WMAA] (Node ffff88007e040120), AE_AML_PACKAGE_LIMIT Would it be possible to improve the driver to prevent these errors? Somewhat related, the value of 'display' seems rather strange: $ cat /sys/bus/platform/devices/hp-wmi/display 65795 Any idea if that's correct or not and what the meaning of that value is?
