Okay. So we've been running 4.4.70 now for 22 hours and counting on docker1-tcn.

This looks promising. But, for this machine to work, I had to switch the dockerd storage from aufs from overlay2, because the vanilla kernel doesn't include aufs. This change isn't a problem, but it makes this result less reliable: is the problem with the Ubuntu-specific modules? Or with something that has been fixed between kernel 4.4.61 and 4.4.70? My best guess is still something with a (filesystem module?) change that went into 4.4.0-78 that did not get (fully) applied to the Ubuntu-specific modules. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1691741 Title: Execute NX-protected page - 4.4.0-78-generic - kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1691741/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
