I'm not sure what's the effect of this OOPS, kernel seems stable so far and I can use /sys/class/rfkill/rfkill0/state to disable/enable bluetooth (it's a desktop computer so no hardware switch). It wasn't a problem on vmlinuz-3.2.0-20-generic so it seems to be a regression related to the latest update ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-21-generic 3.2.0-21.34 ProcVersionSignature: Ubuntu 3.2.0-21.34-generic 3.2.13 Uname: Linux 3.2.0-21-generic x86_64 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
