Intel Mobile Express Chipset SATA AHCI Controller

Hello all,

I'm in the process of trying to setup a Lenovo Ideapad U410 with Fedora
17. The system keeps putting the SATA drive into UDMA/100. Apparently the
system has an Intel Mobile Express Chipset SATA AHCI controller. I have
found next to nothing detailing Linux support for this controller. Does
anyone have experience with this?

I've done the normal steps as far as checking to make sure the BIOS is set
to AHCI and has been since I installed. When the system first boots I get
messages such as "*ata2*.*00*: *failed to enable AA*(error_mask=0x1)" a
couple times as it boots up. Probably going to open a bug report if I
can't find anything else, but I'm not sure if this is a bug or just
unsupported hardware. Any pointers in the right direction on handling this
would be appreciated.

Thanks
Lucas

I seem to recall using the boot options "ide0=noprobe ide1=noprobe" on
CentOS 4 and CentOS5 to prevent the SATA controller from being used as a
legacy (lower performance) IDE controller.
