ACPI video or thinkpad-acpi ? sh-3.2$ grep -i VIDEO .config CONFIG_ACPI_VIDEO=y ...so I think it is ACPI video. sh-3.2$ grep -i THINK .config CONFIG_THINKPAD_ACPI=y # CONFIG_THINKPAD_ACPI_DEBUGFACILITIES is not set # CONFIG_THINKPAD_ACPI_DEBUG is not set CONFIG_THINKPAD_ACPI_UNSAFE_LEDS=y CONFIG_THINKPAD_ACPI_BAY=y CONFIG_THINKPAD_ACPI_VIDEO=y # CONFIG_THINKPAD_ACPI_HOTKEY_POLL is not set sh-3.2$ ...and yes, I think it only happens on reboot.
