I connect SATA Harddisk with OMAP-L138, but it don't work. SATA drives under linux 2.6.32-rc6 is supported? 

It cann't reset successful:

ata1: softreset failed (device not ready)
ata1: limiting SATA link speed to 1.5 Gbps
ata1: softreset failed (device not ready)
ata1: reset failed, giving up

Is this a hardware problem or driver problem?

    I'm having a similar problem (see below), I've tried 2 hard drives which do similar things.  where is the PMAHCI config set? is that something that gets passed into the boot args?

    I got that the first time :)

    Where is this located for me to disable it?

    Is this something that is done as part of the kernel configuration, or is this something that gets passed to the kernel as part of the bootargs?

    Any status on this?  I would think this should be pretty straight forward question to answer.

    Jean,

    Menuconfig -> device drivers->sata -> PM support.

    Pl. disable the PM support.
