This also affects 14.04 LTS, although to a slightly lesser degree. In 14.04 we have a patch which does the modprobing for the "cpu" subsystem; but reportedly this also affects drivers of other platforms, so let's just backport that more generic upstream fix to cover all cases.
This can potentially cause a lot more attempts to load nonexisting modules, and thus affect boot speed a bit. For 14.04 we have a builtin kmod which is really fast to fail, so the impact should be negligible. It might be measurable on 12.04 on some systems, but then again as we do ship backported kernels on 12.04 and officially support them we don't have much choice here. ** Summary changed: - [precise] udev does not automatically load modules with kernel >= 3.11 + [precise, trusty] udev does not automatically load modules with kernel >= 3.11 ** Also affects: systemd (Ubuntu) Importance: Undecided Status: New ** Also affects: udev (Ubuntu Trusty) Importance: Undecided Status: New ** Also affects: systemd (Ubuntu Trusty) Importance: Undecided Status: New ** No longer affects: systemd (Ubuntu Precise) ** No longer affects: udev (Ubuntu Trusty) ** Changed in: systemd (Ubuntu) Status: New => Fix Released ** Changed in: systemd (Ubuntu Trusty) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1404509 Title: [precise, trusty] udev does not automatically load modules with kernel >= 3.11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1404509/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
