ブルースクリーン その２

先日PCをシャットダウンしようとしたらブルースクリーンでクラッシュダンプが実行。
WhoCrashedツールを実行したら下記となった。

Crash dumps are enabled on your computer.


On Thu 2010/03/18 15:12:44 your computer crashed
This was likely caused by the following module: clfs.sys
Bugcheck code: 0xA (0x0, 0x2, 0x1, 0x834EDA40)
Error: IRQL_NOT_LESS_OR_EQUAL
Dump file: C:\Windows\Minidump\031910-17815-01.dmp

product: MicrosoftR WindowsR Operating System
company: Microsoft Corporation
description: Common Log File System Driver
The crash took place in a standard Microsoft module. Your system configuration may be incorrect, possibly the culprit may be another driver on your system which cannot be identified at this time.

このCLFSはCommon Log File Systemらしい。ネットで検索すると
ブルースクリーン（0x0000C1F5）はHDDの＄TxfLogファイルが破損している、らしいが
0xAなのでちょっと様子が違うようだ。
ログファイルなら1度削除して、しまえば良い様に思えるが･･･
もっと検索したら下記がMSの資料で見つかった。

Bug Check 0xA: IRQL_NOT_LESS_OR_EQUAL

The IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x0000000A. This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.
Parameters

The following parameters are displayed on the blue screen.
Parameter Description
1 Memory referenced
2 IRQL at time of reference
3 0: Read

1: Write

4 Address which referenced memory

Cause

This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high.

The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.

If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version.
Resolving the Problem

どうやらおかしな動作をするドライバの問題のようだ。
デバッガでドライバを突き止めて、使用不可にするといいらしいが･･･
