Hi,
I did some bisecting (10 successful boots == good) and got this:
30dcf76acc695cbd2fa919e294670fe9552e16e7 is the first bad commit
commit 30dcf76acc695cbd2fa919e294670fe9552e16e7

libata: migrate ACPI code over to new bindings
Now that we have the ability to directly glue the ACPI namespace to the
driver model in libata, we don't need the custom code to handle the same
thing. Remove it and migrate the functions over to the new code.

I've also added some prints:
pacpi_port_start is called before pacpi_qc_issue but ata_do_set_mode is called
after pacpi_qc_issue.. that seems not right, right?
Hope this will help someone familiar with that code..
I'll upload full dmesg as well.
