Looking at this again, I guess I'm a bit confused. The
IOCTL_KS_RESET_STATE command should be handled by the port class port
driver. I don't think it feeds down to the miniport at all.
The key thing this seems to be complaining about is that your driver
allowed a "write" to occur even though it is paused. Again, I'm not
sure that is under your control. The MSVAD driver only checks for the
"paused" state in a very few circumstances.
