OK, other than the dkms issues, 4.2.0 rc8 did install enough to boot (just didn't have wifi), and it does boot in SMP mode:
bladernr@Bun-Bun:~$ uname -a Linux Bun-Bun 4.2.0-040200rc8-generic #201508240030 SMP Mon Aug 24 04:31:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux bladernr@Bun-Bun:~$ cat /proc/cpuinfo |grep ocessor processor : 0 processor : 1 processor : 2 processor : 3 so with 4.2.0 rc8, at least, I can boot in SMP mode, and all four CPUs appear (two cores at 2 threads each). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1487621 Title: Fails to boot on Macbook Air 2013 (Haswell) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1487621/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
