Phew ... at last for once the kernel didn't crash, restarted the machine twice and checked while performing the steps mentioned below.
1) Connected using PPPOE to mobile phone modem through USB 2) Connected using PPPOE to mobile phone modem through Blue-tooth 3) Disconnected and reconnected both multiple times 4) Also checking & un-checking "Enable Networking" while performing the above steps The computer didn't crash, no kernel panic errors, nothing. But I was checking the Logs in "/var/log" folder & I noticed that in both "kern.log + syslog" there is some unusual activity in the new Test Kernel, while the older stable 3.7.10 seemed a calm to my liking. I'm sure it will be of interest to you, so am attaching the logs for both kernels. //Note: I will be out of station for 15 days from 03Jun2013 (will be climbing some mountain), so I wont be able to test any kernels till at- least 18Jun2013. Looking forward for 3.10 / 3.11 kernel without this nasty bug. Thanks in advance. ** Attachment added: "Kernel_Logs_01Jun2013.zip" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/+attachment/3692050/+files/Kernel_Logs_01Jun2013.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1144322 Title: Kernel Panic in 3.8.0, 3.8.1 & 3.8.2 when diconnecting from network manager, using ppp0 to connect to net To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
