Those spurious interrupts are because ata1 share irq15 with USB.
Most HW was not designed for this. If its a problem that they get printed
dont bot verbose or comment out the prints in ata-lowlevel.c

There is a problem in the kernel that makes the console lockup if there
is too much printed too fast from inside the kernel..
