Sorry for the delay, I just got back from a couple of weeks on another continent so didn't feel like testing this remotely :) I'll do a test run now. By the way, since I first reported this issue, I managed to reproduce it on two more machines running the 3.11 kernel, it seems to vary with the number of netfilter rules loaded, the more you have, the more likely it's to panic (or something along those lines). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1251946 Title: Network related kernel panic on Atom 64bit system using saucy backport stack on precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1251946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1251946] Re: Network related kernel panic on Atom 64bit system using saucy backport stack on precise
I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue. Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: v3.3 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-precise/ v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/ v3.5 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-quantal/ v3.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/ v3.7 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/ You don't have to test every kernel, just up until the kernel that first has this bug.

[Bug 1251946] Re: Network related kernel panic on Atom 64bit system using saucy backport stack on precise
I've been running the standard backported 3.5 kernel for an hour without getting a panic. I'm currently running a 3.11 debug kernel from Andy, once that one panics (probably in the next hour), I'll then try the 3.6 and 3.7 you linked above to try and figure out when the issue was introduced. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1251946 Title: Network related kernel panic on Atom 64bit system using saucy backport stack on precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1251946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can you test the following kernels and report back?
