I'm trying to install Linux on the new April 2016 MacBook 12" (A1534).
Booting from USB via EFI works fine: I tried Arch Linux (2016.05.01, kernel 4.5.1) and Ubuntu (16.04, kernel 4.4.0-21; and Lubuntu 15.10). I had to pass the kernel options
noapic in the Arch Linux case and
noapic acpi=off noacpi nomodeset in the Ubuntu case – otherwise the screen stays blank and the kernel doesn't boot.
Even the wireless card works out-of-the-box (Broadcom BCM4350 802.11ac 14e4:43a3). Also suspend-to-RAM works. (Keyboard and touchpad don't work, but these are not my priority at the moment.)
However, the kernel doesn't detect the built-in flash drive (the MacBook doesn't have a further storage medium). That is,
cat /proc/partitions do not show any entries pertaining to the flash drive. Based on suggestions for older MacBooks, I loaded the kernel module
nvme, and, since the flash drive reports an incorrect PCI device class, manually bound it with:
echo 106b 2003 > /sys/bus/pci/drivers/nvme/new_id
The dmesg output is non-informative, it just reports that the probe failed. The flash drive reports under
lspci -nn as:
01:00.0 Mass storage controller : Apple Inc. Device [106b:2003] (rev 11)
Note that this is different from previous versions of the MacBook (where the PCI ID was 106b:2001). The flash drive is detected from the Grub shell and works just fine from Mac OS X.
What should I try next? I'm hoping that there are indeed further suggestions, at this point I'm at a loss.
