| 总是偶然出现的蓝屏,能力有限,无法判断该如何处理,来求教各位前辈高手!   CurIRQL = KeGetCurrentIrql();Crach Dump的指示似乎总是这一句的问题,但是这句如何导致空地址访问的呢? 而且IROL又是一个CLOCK2_LEVEL的代码。
 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: 00000000, memory referenced
 Arg2: 0000001c, 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: 804f9913, address which referenced memory
