[Bug 1144322]
I think we finally have a winner patchset here.
On Linux-Bluetooth there are two patches that showed up that, when
patched against 3.12.6, seemingly completely fixes the longstanding
problem. I don't know when these will show up in mainline.
The patch names are "rfc3.patch" and "modman.patch" from Gianluca
Anzolin. I'll attach the patches here.
Thanks for all of Gentoo staff for tolerating bugs like this. I've been
posting in the Ubuntu forums about this and all I get is flak.

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:
New
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. Think there is some REGRESSION in Kernel 3.8
below details are provided using "HardInfo 0.5.1" :
