In that case, it will avoid renew DHCP lease. ifplugd doesn't renew DHCP leases anyway, one of the scripts it invokes does. ifplugd is obsolete software. I wrote it more than 10 years ago, and haven't really updated it since. it's sounds seriously wrong to add multi-second waits to the kernel just to make this crappy, obsolete software work. Please fix this properly, and work with the PM guys, so that we get a sane userspace how the kernel can notify userspace about suspends/hibernations triggered from the outside, so that userspace daemons can subscribe to that and then refresh the DHCP leases on their own.
