These symptoms sound very much like https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842447 (I found the bug I'm commenting on while searching for additional links about the issue in 1842447). There's a -62 kernel in proposed updates which hopefully contains the fix for this bug. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842447 for hints on how to install the proposed update kernel.
So far the trigger is sounding like NAT + 4.15.0-60 kernel + sufficient time that the relevant uninitialised variable is not clean from boot. I think this is the fix in -62: https://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git/commit/?h=master- next&id=b502cfeffec81be8564189e5498fd3f252b27900 Ewen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843152 Title: Kernel Panic with linux kernel 4.15.0-60 possibly related to network subsystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1843152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
