Kernel module "libahci" not loaded with a newer SATA controller

Reported by: Manuel Carreira Silva Owned by: Bruno Cornec
Priority: normal Milestone:
Component: mindi Version:
Severity: normal Keywords: libahci sata cdrom


When booting from a mindi cd in a HP Pavilion DV8 laptop, the CDROM is not found, and breaks everything.
The reason is that "libahci" kernel module is not loaded and "ahci" module depends on this one.
So, after FORCE_MODS="libahci" the problem is solved.
But... I looked for mindi logs in other computers with SATA disks, and the "libahci" module was loaded automatically without beeing forced.
Why is this happening with this computer?
A SATA disk is not a rare piece of hardware that we must force to load the driver.
If this is a new SATA controller, maybe other new computers will be build with this hardware.

My question is:

Wouldn't it be better to include "libahci" driver to IDE_MODS variable in /usr/sbin/mindi?

This is SATA lspci output from HP DV8:

mindi adds libahci automatically if it's mounted at backup time, which is the case when it's a HDD, but generally not when it's a CD.

libahci was added as a dep in rev [2737]
