In fact, I don't know how to upgrade my kernel to version 3.0.0-12.20, I just install the package from https://launchpad.net/ubuntu/+source/linux/3.0.0-12.20/+build/2829179/+files /linux-image-3.0.0-12-generic_3.0.0-12.20_amd64.deb.
The package info: Package: linux-image-3.0.0-12-generic Status: install ok installed Priority: optional Section: admin Installed-Size: 148744 Maintainer: Ubuntu Kernel Team <[email protected]> Architecture: amd64 Source: linux Version: 3.0.0-12.20 Provides: fuse-module, ivtv-modules, kvm-api-4, linux-image, linux-image-3.0, ndiswrapper-modules-1.9, redhat-cluster-modules Depends: initramfs-tools (>= 0.36ubuntu6), coreutils | fileutils (>= 4.0), module-init-tools (>= 3.3-pre11-4ubuntu3), wireless-crda Pre-Depends: dpkg (>= 1.10.24) Recommends: grub-pc | grub-efi-amd64 | grub-efi-ia32 | grub | lilo (>= 19.1) Suggests: fdutils, linux-doc-3.0.0 | linux-source-3.0.0, linux-tools Conflicts: hotplug (<< 0.0.20040105-1) Then I perform this testing: 1. Attach an external bluetooth adapter. bt-adapter -l: Available adapters: Accel-OB2 (00:1F:81:00:02:50) 2. Connect a bluetooth mouse (maybe other devices have the same problem) with the adapter bt-device -l: Added devices: VGP-BMS33 (00:02:76:1F:23:76) 3. Disconnect the bluetooth mouse using "bt-device -d VGP-BMS33". 4. Reconnect the bluetooth mouse with the adapter(It will auto-connect again after I execute step 3.). 5. Repeat "step 3-4" several times, the system will crash to console with some Tainted info. Test result: the system will crash to console with some Tainted info. Please notice that the bluetooth mouse will auto connect the adapter if it has been disconnected. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/837379 Title: NULL pointer dereference at 0000000000000039 (sysfs_create_dir+0x35) when resuming after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/837379/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
