Hello, I'm currently on the 3.8.0 kernel with Ubuntu 13.04 (Raring) x64 on a Thinkpad x201. I have hibernation enabled by following the instructions in the official Ubuntu documentation[1]. If Bluetooth is disabled before hibernation, on resume it will be re-enabled. I have the latest BIOS installed (1.40-1.15)[2], and can reproduce this issue with the latest mainline kernel available to me (v3.11-rc3-saucy)[3]. I didn't experience this issue with the 3.5.0 kernel (with Ubuntu 12.10 Quantal), so it appears to be a regression. I've done a bisection with this result: > a57f7f9175b8ccbc9df83ac13860488913115de4 is the first bad commit > commit a57f7f9175b8ccbc9df83ac13860488913115de4 > Author: Bob Moore
