Keerthy noticed this may not happen on the first resume, but usually happens after few suspend resume cycles. The most working suspend resume cycles I've seen with the commit above is three. Any ideas what might be going wrong? Note that unrelated to the commit above, there may be other issues too as the cpsw phy LED seems to come on only after about five seconds with about total of 10 seconds before the Ethernet is up again.
