Queuing Irp

NTDEV
1

How long one can delay the Irp read requests before completion?
During system boot, I queue the Irp as follows:

IoMarkIrpPending(Irp);
InsertTailList(&(PDeviceExtension->PendingIrpList),&(Irp->Tail.Overlay.ListEntry));
return STATUS_PENDING;

There after the system freezes

Any clues as to what might be happening?

During system boot, I queue the Irp as follows:

In general, the time is not limited at all, but some particular stacks can have limitations.
What it this stack?

The stack in question is storage. However it is not a boot/system drive.
