Install help on Lenovo Yoga 300-11IBY

[Ian]

Thank you Matt, adding the sdhci_acpi.ko module fixed it for me.

For the benefit of others who may not have done this before these are the steps I had to take to get my fresh 4.8 install to boot on a Lenovo Yoga 300 11iBY
It’s an Atom powered netbook with 32Gb MMC ‘SSD’ drive.

After install the machine will reboot and you are presented with the DragonFly boot screen.

Press ESC to stop the countdown.

You’ll see the OK prompt, it’s here we need to load a few kernel modules so the internal drive can be recognised.

Type the following in this order
load kernel
load mmc
load mmcsd
load sdhci_acpi

You may need to load more modules for your machine.

When you’re done loading modules type:
boot

Which will then boot the system

Or 
boot -v

Which will boot the system, and show you more detailed messages which may help with troubleshooting.

I’m now up and running and DF is fast on this little laptop!

As Matt and the docs mention if you’re using Hammer FS it’s important to prune data frequently on smaller drives like these as Hammer will store backups and may fill your drive up quickly.

Thanks,
Ian
