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