If it is an old card (without the 12V drive power cable connector), stop
*, unload the modules, reload them, restart *.  That will fix it.

You are probably sharing an interrupt with the card and something else in
your machine.  Get it onto its own interrupt.  That fixed the problem for
me.  My guess is that the driver isn't smart enough to notice this failure
and reinitialize the card.
