** Description changed: - Using: "Ubuntu 12.04 (precise) 32-bit" - Machine: Laptop / old Toshiba / Celeron processor + 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. - - PROBLEM ############################################# - Machine connects to net using "ppp0" (modem on phone), then if you disconnect the modem "ppp0" & try to reconnect, the Kernel Panics & crashes. + 10.04).

Machine connects to net using "ppp0" (modem on phone), then if you - disconnect by unchecking "Enable Networking" & then rechecking "Enable - Networking", the Kernel Panics & crashes. - - #################################################### + 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 - I really apologize for not able to provide Apport logs as I have - uninstalled it a long time ago. I'm not a hard core techie, I'm self - taught Linux user & enthusiast. My main machine is Ubuntu since 2007. - - - - - - - _________________________________________________ - below details are provided using "HardInfo 0.5.1" : - - ComputerSummary - Computer - Processor Intel(R) Celeron(R) M processor 1.40GHz -

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" : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/+attachment/3761201/+files/hardinfo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
