That would indeed put processes in uninterruptable IO, since the kernel
will refuse to let processes run while it's waiting for a response from
the hardware.

Try using the same hardware but with a different kernel (Windows or Linux)
that has another driver. If the driver *or* the controller is broken,
you'll get unkillable processes.

If the raid hardware is broken, you need to replace the hardware.
If the BSD raid driver is buggy, you need to either get new (and better
supported) hardware, or change the OS.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
