Hey Guys, I also experienced this bug and was unable to boot completely with 3.19 kernel. Thus I gave the current upstream linux kernel (4.1-rc2) a try and it works like a charm on every single boot. Couldn't be better.
Some more background: I started with Lubuntu 14.10 (3.13 kernel) on my good old MacBook 2,1 (late 2007). Then followed the official release line to 15.04 (3.16 kernel). Both kernel versions occasionally crashed during boot. After rebooting ~5 times or so they worked :). Behaviour was always the same: On first boot, there was just a black screen. The following reboots showed error messages related to the RTC and keyboard bus (sorry, I don't remember exactly). Even on a successful boot, sometimes these messages were shown (not on every boot !?). With the current upstream kernel, those problems are completely past. If you want to try that and have VirtualBox installed, you need to uninstall that first (the DKMS part at least). Same is valid for other installed kernel modules. Otherwise the kernel will not boot. However, this is also stated in the ubuntu docs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1455852 Title: 15.04 will not boot on MacBook 2,1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1455852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
