AFAIK, RQ_INACTIVE means that you tried to queue a SCSI command, when there
is no request pending.

something like
spin_lock_irqsave (&io_request_lock, flags);
REAL_IRQ_HANDLER();
spin_unlock_irqrestore (&io_request_lock, flags);
RETURN;
Make sure the restored flags are the same than the saved ones.
This means, that they need to be local (per-CPU) on the stack and not a
global variable.
