我们得到了一个随机停止的框IRQL_NOT_LESS_OR_EQUAL。我们得到了一个完整的内存转储。
这显然与网络有关。我该如何深入研究这个问题以找出确切的罪魁祸首（如果可能的话）？
几个月前，系统从 Windows Embedded Standard 7 升级到 Windows 10 IoT LTSC 2019。升级之前，它运行良好。

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: 00000020, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000002, 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: e1ab478f, address which referenced memory
