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 an invalid address while at a raised interrupt request level (IRQL). This is typically the result of either a bad pointer or a pageability problem.

Important

This topic is for programmers. If you are a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors.

IRQL_NOT_LESS_OR_EQUAL parameters

Parameter Description

1

The virtual memory address that could not be accessed.

Use !pool on this address to see whether it's paged pool. These commands, may also be useful in gathering information about the failure: !pte, !address, and ln (list nearest symbols).

2

IRQL at time of the fault.

VALUES:

  • 2: The IRQL was DISPATCH_LEVEL at the time of the fault.

3

Bit field that describes the operation that caused the fault. Note that bit 3 is only available on chipsets that support this level of reporting.

Bit 0 values:

  • 0 - Read operation

  • 1 - Write operation

Bit 3 values:

  • 0 - Not an execute operation

  • 1 - Execute operation

Bit 0 and Bit 3 combined values:

  • 0x0 - Fault trying to READ from the address in parameter 1.

  • 0x1 - Fault trying to WRITE to the address in parameter 1.

  • 0x8 - Fault trying to EXECUTE code from the address in parameter 1.

This value is usually caused by:

  • Calling a function that cannot be called at DISPATCH_LEVEL while at DISPATCH_LEVEL.
  • Forgetting to release a spinlock.
  • Marking code as pageable when it must be non-pageable (for example, because the code acquires a spinlock, or is called in a deferred procedure call).

4

The instruction pointer at the time of the fault.

Use the ln (list nearest symbols) command on this address to see the name of the function.

Cause

This bug check is usually caused by kernel-mode device drivers that use improper addresses.

This bug check indicates that an attempt was made to access an invalid address while at a raised interrupt request level (IRQL). This is either a bad memory pointer or a pageability problem with the device driver code.

Following are some general guidelines that you can use to categorize the type of coding error that caused the bug check:

  • If parameter 1 is less than 0x1000, the issue is likely a NULL pointer dereference.

  • If !pool reports that parameter 1 is paged pool (or other types of pageable memory), then the IRQL is too high to access this data. Run at a lower IRQL, or allocate the data in the nonpaged pool.

  • If parameter 3 indicates that this was an attempt to execute pageable code, then the IRQL is too high to call this function. Run at a lower IRQL, or do not mark the code as pageable.

  • Otherwise, this may be a bad pointer, possibly caused by use-after-free or bit-flipping. Investigate the validity of parameter 1 with !pte, !address, and ln (list nearest symbols).

Resolution

If a kernel debugger is available, obtain a stack trace. Start by running the !analyze debugger extension to display information about the bug check. (The !analyze extension can be helpful in determining the root cause.) Next, enter one of the k* (display stack backtrace) commands to view the call stack.

Gather Information

Examine the name of the driver if that was listed on the blue screen.

Check the System Log in Event Viewer for additional error messages that might help pinpoint the device or driver that is causing the error. Look for critical errors in the system log that occurred in the same time window as the blue screen.

Driver Verifier

Driver Verifier is a tool that runs in real time to examine the behavior of drivers. For example, Driver Verifier checks the use of memory resources, such as memory pools. If it identifies errors in the execution of driver code, it proactively creates an exception to allow that part of the driver code to be further scrutinized. Driver Verifier Manager is built into Windows and is available on all Windows PCs.

To start Driver Verifier Manager, type verifier at a command prompt. You can configure which drivers to verify. The code that verifies drivers adds overhead as it runs, so try to verify the smallest number of drivers as possible. For more information, see Driver Verifier.

Remarks

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 newer version of Windows, the 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 a faulty hardware problem: If hardware has been added to the system recently, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. Run hardware diagnostics that are supplied by the system manufacturer. For details on these procedures, see the owner's manual for your computer.

Resolving a faulty system service problem: Disable the service and confirm whether doing so resolves the error. If so, contact the manufacturer of the system service about a possible update. If the error occurs during system startup, investigate the Windows repair options. For more information, see Recovery options in Windows 10.

Resolving an antivirus software problem: Disable the program and confirm whether doing so resolves the error. If it does, contact the manufacturer of the program about a possible update.
