CONFIG_APM_ALLOW_INTS: Allow interrupts during APM BIOS calls

General informations

The Linux kernel configuration item CONFIG_APM_ALLOW_INTS has multiple definitions:

Allow interrupts during APM BIOS calls found in arch/i386/Kconfig

The configuration item CONFIG_APM_ALLOW_INTS:

• prompt: Allow interrupts during APM BIOS calls
• type: bool
• depends on: CONFIG_APM
• defined in arch/i386/Kconfig
• found in Linux kernels: 2.6.0–2.6.23

Help text

Normally we disable external interrupts while we are making calls to the APM BIOS as a measure to lessen the effects of a badly behaving BIOS implementation. The BIOS should reenable interrupts if it needs to. Unfortunately, some BIOSes do not -- especially those in many of the newer IBM Thinkpads. If you experience hangs when you suspend, try setting this to Y. Otherwise, say N.
