rtsx_usb_ms creates a task that mostly sleeps, but tasks in uninterruptible sleep still contribute to the load average (for bug-compatibility with Unix). A load average of ~1 on a system that should be idle is somewhat alarming.
Change the sleep to be interruptible, but still ignore signals. A better fix might be to replace this loop with a delayed work item.
