Thanks for testing, Till. I'd next try to identify which 3.11 release candidate introduced the regression.
Can you test the following kernels and report back? We are looking for the earliest kernel version that exhibits this bug: v3.11-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy v3.11-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc2-saucy v3.11-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc3-saucy/ v3.11-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc4-saucy/ You don't have to test every kernel, just up until the kernel that first has this bug. Thanks in advance! ** Tags added: performing-bisect -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1213239 Title: Bluetooth subsystem dies after suspend Status in “linux” package in Ubuntu: Incomplete Bug description: I am using Saucy in XMir mode with the standard Unity desktop on the Lenovo Thinkpad Twist. When I suspend the system not only the suspend itself is broken (bug 1213233) but also after waking up I cannot use my Bluetooth devices any more (mouse, keyboard). I have to reboot to get Bluetooth back working. Do not ask me to update the BIOS from 1.52 to 1.57, this leads to bug 1210748.
