急急 ， PLX9054 DMA 的奇怪问题，

现在在用DS3.2写一个 pci9054 的驱动， 其中包含了DMA。做此部分时，也主要是参考了武安和的例子。
  可是在DPC中 执行m_CurrentTransfer->Continue(UseTransferSize); 时，老是崩掉，用Windbg查看，都是DRIVER_IRQL_NOT_LESS_OR_EQUAL 的问题， 访问了nonpage的内存。

   此问题应该很多人都遇到了，比如：
   http://bbs.driverdevelop.com/htm_data/11/0405/67356.html
     此位实验出是 队列的 问题，用驱动程序管理的队列就会出错。

   我本想也试试系统管理的队列，但是应该是由于DS版本的问题，现在的DS3.2，如果在wizard中要指明用到Queue时，都是由驱动程序管理的，不然的话，假如在wizard指明不用queue生成的代码中，没有serialread serialwrite。所以现在陷入了两难，既无法实验上面那位的成果，现在的办法也走不通。


  下面附上出错的结果。

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 9adc9f4c, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 804efd80, address which referenced memory

不知道你想说什么。

我以前也用DW3.2写的9054，DMA很正常。

你代码有问题。
