Yes, the 4000+ is 2.4GHz.

Ouch.  Sounds like that's where your problem is.  If you have
fluttering bus arbitrators/controllers, then that absolutely
kills performance.

Yep, there are your modes.  Again, your 4000+ is a 2.4GHz.

Hmmm, are you getting any ATA timeouts after the system is
booted?

There are no further entried in the dmesg output after booting
So it would not seem that there are any ATA timeouts...

Is there something else to check?
