            Bug ID: 185531
           Summary: pata_hpt366 irq xx: nobody cared
           Product: IO/Storage
           Version: 2.5
    Kernel Version: Linux 4.4.0-45-generic Ubuntu SMP x86_64
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: IDE
          Assignee: io_ide@kernel-bugs.osdl.org
          Reporter: ilario.gottardello@gmail.com
        Regression: No

Some time after boot, a spurious interrupt make this driver downgrade
performance from udma to pio. This interrupt is assigned solely to this card,
as says /proc/interrupts:

           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5      
CPU6       CPU7
 19:       4147          0          0        188     195666          0         
0          0   IO-APIC  19-fasteoi   pata_hpt366, pata_hpt366

This is the relevant part from dmesg:

Already changed cables and moved the card in another slot, the issue still
appears.
I'm willing to help debug the issue. Thanks in advance.
