any chance you could obtain additional debugging output by turning on

#undef ATA_VERBOSE_DEBUG        /* yet more debugging output */

in include/linux/libata.h? this would help us see where it is stuck in 'D' state.

Recompiled only the driver after modification and the output is:

I don't think that this is really what you wanted - you probably wanted the place in libata where insmod stops, but the root FS is on another SATA disk connected to the ICH6, so if I enable DEBUG for libata this controller/disk will log quite a lot, right ?

Also, you might try turning off CONFIG_PCI_MSI, in case MSI is problematic on your machine, or on this card.

I'll try, but this requires recompiling the kernel. But I'll wait for the confirmation on whether the whole libata should be DEBUG-ed before starting the recompilation.
