Gurvender.Bahia, one would need to be using a Ubuntu repository kernel to run the apport-collect. As per https://launchpad.net/ubuntu/+source/linux , for Precise this would be 3.2.0-51.77.

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
