There can be several causes:
a) the adapter has a bug with interrupts handling
b) the driver has a bug 
c) the hardware (drives, cables) don't play nice together

As far as I can tell the interrupt routine in the driver is OK, but I don't
have programming docs for this adapter. c) can be caused by interferences
between the 2 cables, or by interferences on the power supply lines if
the PS isn't good enouth.
