I can confirm that 3.13.0-63 kernel works. If you rely on this functionality, editing GRUB_DEFAULT to something like "Advanced options for Ubuntu>Ubuntu, with Linux 3.13.0-63-generic" is a graceful way to downgrade kernel in the interim. You can list available kernels with "cat /boot/grub/grub.cfg | grep menuentry". Just run update-grub to apply, then reboot. I'd then recommend subscribing to this bug for updates so you don't forget to revert grub settings once it's fixed.
I didn't have 3.13.0-63 available on my system until I manually installed the packages (linux-headers-3.13.0-63 linux- headers-3.13.0-63-generic linux-image-3.13.0-63-generic linux-image- extra-3.13.0-63-generic linux-signed-image-3.13.0-63-generic). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1501345 Title: linux-image-3.13.0-65-generic 3.13.0-65 breaks Python based Serial communication To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1501345/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
