Comment 35 for bug 1566828

Noticing everyone in this bug report has Intel + Radeon graphics, I tried disabling the Radeon. Simply running 'sudo rmmod radeon' after the laptop boots up with the stock 4.4 kernel allows it to properly sleep. Removing the kernel module causes kernel oops, but otherwise everything seems fine after unloading it. I've attached a dmesg showing the kernel module removal with the oops, and the successful sleep/wake that follows it. I've tried it several times and sleep/wake is working every time after removing radeon, and fails every time while radeon is loaded.
