Got the newest Macbook Air 11" with 8gb memory and wanted to report my results.
tl;dr It is possible to install, though there are at least a few things not working.
The biggest hurdle that I encountered was the install CD halting with:
I was able to work around by adding "nointremap" to the boot options. From what I've read about that option, it is not a good thing to use, but it allowed the install CD to work (manually edited the boot options) and it allows the OS to boot once installed.
kernel panic not syncing timer doesn't work through interrupt-remapped io-apic
That is, instead of:
I am using:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.i915_enable_rc6=1 resume=/dev/sda5"
I have a superdrive, so I cannot speak to USB install, but I would guess that it still works.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nointremap i915.i915_enable_rc6=1 resume=/dev/sda5"
I ran through the post-install script manually and most of it worked. In particular, the updated wl network drivers still work for quick connectivity.
What is not working:
- applesmc. Modprobe-ing that results in an input-output error. I'm not sure how big a deal that is.
- Keyboard lights. I prefer them off so I have not investigated.
- Fn key to dim the screen (the brightness applet works). Oddly the fn key to brighten the screen does work.
What is working: suspend (mouse was messed up, but that could just be me), reboot, most keyboard functions, touchpad (with synaptics), wireless, camera, sounds.
Haven't tested yet: OSX partition access, microphone, fan control, extra power saving, external monitor (I don't use one).
All-in-all, I think this is going to be an excellent Ubuntu machine
