Subject: Ask devices to powerdown before S3 sleep
Date: Sun, 19 Jan 2003 22:46:42 +0100 [thread overview]
Message-ID: <20030119214642.GA27885@elf.ucw.cz> (raw)
Hi!
SUSPEND_RESUME phase is needed for turning off IO-APIC. [I believe
SUSPEND_DISABLE should be so simple that errors just should not be
there, and besides we would not know how to safely enable devices from
such weird state, anyway]. Please apply,
Pavel
