I've tried 3.12-rc2, as far as I can tell just opening and closing the rfcomm in BT seems to no longer crash the box - however, some characteristics changed and NetworkManager no longer accepts /dev/rfcomm* as a valid communications device as before, so I can't fully test it.
A bit tricky - using the same userland, Linux-3.5.7-gentoo - works flawlessly Linux-3.8.13-gentoo - crashes when BT rfcomm is closed Linux-3.12-rc2 (raw from kernel.org) - blueman able to set up rfcomm but networkmanager does not notice that rfcomm was setup. Supposedly NM should notify blueman via dbus that it acknowledges the device, but blueman times out waiting and NM does not recognize the device. In trying to diagnose the problem I tried using busybox microcom on /dev/rfcomm0 directly. I was able to send my modem AT commands like on previous kernels, indicating the bluetooth link indeed works. I was able to shutdown the rfcomm link on blueman as well after sending those bytes through. No crash - a positive sign... but it may depend on the number of bytes sent. I'll need to see why NM does not like the rfcomm device now, but I am no NM or dbus expert... -- 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/1144322 Title: [Toshiba Satellite A80] Kernel 3.8.x Panic when disconnecting from network manager via ppp0 Status in “linux” package in Ubuntu: Incomplete Status in “linux” package in Arch Linux: New Status in Gentoo Linux: Unknown Bug description: Using: "Ubuntu 12.04 (precise) 32-bit" Machine: Laptop / old Toshiba / Celeron processor Installing Kernel from: "http://kernel.ubuntu.com/~kernel-ppa/mainline/"; Apport disabled and uninstalled, so can't provide debug/log details (this to make the machine run a bit faster, have been doing so since 10.04). Have no problem with Kernel upto 3.7.10 (have been upgrading to Kernel 3.5/3.6/3.7/3.8, when ever new builds are available) But when using Kernel 3.8.0/3.8.1/3.8.2, get Kernel Panic & machine crashes & freezes, have to hard boot. Machine connects to net using "ppp0" (modem on phone), then if you disconnect the modem "ppp0" & try to reconnect, the Kernel Panics & crashes, or then if you disconnect by unchecking "Enable Networking" & then rechecking "Enable Networking", the Kernel Panics & crashes. First faced this problem with Kernel 3.8.0 so went back to using 3.7.9, then same story repeated with Kernel 3.8.1 & 3.8.2, currently using Kernel 3.7.10.
