commit 391153522d186f19a008d824bb3a05950351ce6c upstream. The IMR was assumed to be preserved when suspending to S4 and S5 states, but community reports invalidate that assumption, the hardware seems to be powered off and the IMR memory content cleared. Make sure regular boot with firmware download is used for S4 and S5.
