[...] You can force ahci to be loaded first: 1. Add the line 'ahci' to /etc/initramfs-tools/modules. 2. Run 'update-initramfs -u' to regenerate the initramfs. 3. Reboot. But it seems like it would be better if ahci was automatically preferred. Ben. -- Ben Hutchings Once a job is fouled up, anything done to improve it makes it worse.
