Sorry it's taken me so long to get back to you; the affected system is my main work computer, so I can't just go rebooting it constantly, and I've been busy with other things.
In any event, I'm afraid I haven't had much luck with these newer kernels. The bottom line is that to get the VirtualBox modules installed, I need the linux-headers-{version}-generic package, and for these newer kernels, that package depends on libssl1.1 or greater; but the 16.04 I'm using ships with libssl1.0, and I'm unwilling to upgrade that package and risk far greater (and worse) problems or a return to the old "dependency hell" issues of the 1990s. If I get the chance, I may try installing bionic on a removable drive and try to reproduce the problem in that way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748901 Title: System hang with Virtualbox & kernel 4.13.0-32-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1748901/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
