This is still broken. The ARM64 installer can't do anything because it
can't mount any drives including the installation medium because the
ahci modules are not present.
Images tried:
16.04.1 LTS (ubuntu-16.04.1-server-arm64.iso)
Nightly (zesty-server-arm64.iso) - 2017-02-10
** Changed in: linux (Ubuntu)

Title:
[arm] Missing AHCI driver in Ubuntu Xenial Installer for ARM
Status in linux package in Ubuntu:
Confirmed
Bug description:
Download the media installation ISO file at
https://www.ubuntu.com/download/server/arm and burn it to a CD-ROM. Then, put
it into the SATA CD drive to install Ubuntu into Mustang/Merlin boards (XGene
platform), the Installer does not detect the CD-ROM so it report a dialog with
below content:
"Your installation CD-ROM couldn't be mounted. This probably means that the
CD-ROM was not in the drive. If so you can insert it and try again. Retry
mounting the CD-ROM?".
Investigate more on the installer media, I found that the AHCI driver is not
enabled.
Below steps I have done to check:
- Mount ISO file and copy initrd.gz:
# mkdir mnt
# mount -o loop ubuntu-16.04.1-server-arm64.iso ./mnt
# cp ./mnt/install/initrd.gz .
- Extract initrd.gz:
# gunzip initrd.gz
# cpio -id < initrd
- List the drivers/ata folder
# ls lib/modules/4.4.0-31-generic/kernel/drivers
block gpio gpu hid i2c input media mfd power regulator rtc usb
video
No lib/modules/4.4.0-31-generic/kernel/drivers/ata folder exist.
Try to check with x86 installer media:
# ls lib/modules/4.4.0-31-generic/kernel/drivers/
ata block char firewire gpio gpu hid hv i2c infiniband input media
mfd net parport pcmcia power regulator rtc scsi tty usb video
# lib/modules/4.4.0-31-generic/kernel/drivers/ata/ | grep ahci
acard-ahci.ko
ahci.ko
ahci_platform.ko
libahci.ko
libahci_platform.ko
Can you help to add AHCI support for Ubuntu ARM Media installer?
Thanks,
Thang Q. Nguyen
