I changed the kernel config:

   - CONFIG_PCI_MSI=y
   + # CONFIG_PCI_MSI is not set

In other words I disabled Message Signaled Interrupt support.  Now 
instead of "do_IRQ: 0.83 No irq handler for vector" I get:

   +------ PCI-Express Device Error ------+
   Error Severity          : Uncorrected (Non-Fatal)
   PCIE Bus Error type     : Transaction Layer
   Flow Control Protocol   : First
   Receiver ID             : 0010
   VendorID=1106h, DeviceID=a208h, Bus=00h, Device=02h, Function=00h
   Broadcast error_detected message
   Broadcast mmio_enabled message
   Broadcast resume message
   AER driver successfully recovered

(Repeated as many times as the "do_IRQ" message previously.)

In case someone needs it, this is my complete dmesg:

and this is the kernel configuration:
