[PATCH] sky2: stop/start hardware idle timer on suspend/resume
The resume bug was caused not by an early interrupt but because the idle timeout was not being stopped on suspend. Also disable hardware IRQ's on suspend. Will need to revisit this with hotplug? Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
