    Unfortunately there are 1001 different causes for timeouts, so we need 
    to drill down into the hardware, libata version, and ACPI version (most 
    notably).

    There was also an ACPI update, which always affects interrupt handling 
    (whose symptom can sometimes be a timeout).
    
    Definitely interesting in test results from what you describe.
