Q.
I recently got a couple of BSOD's with the 0x000000D1 error,
irq_not_less_or_equal. I ran the debugging app that Microsoft offers and
it found out that the wanarp.sys is to blame for the error. But this information
was already displayed on the blue screen. I checked, and the service
corresponding to that file is disabled. At this moment, I ran out of ideas. My
memory dump was set for kernel dump, but now I set it to minidump, so I can
attach some minidump files after the next BSOD. Because it will happen.
A.
Go here and download "autoruns" (freeware):
http://www.microsoft.com/technet/sysinternals/Utilities/AutoRuns.mspx
Run the .exe and see if the
driver for wanarp.sys is being loaded at boot even
if the service is disabled.
You'll be surprised how many items are loaded upon boot.
Here's the scoop on the BSOD:
Stop 0x000000D1 or DRIVER_IRQL_NOT_LESS_OR_EQUAL
The Stop 0xD1 messages indicates that the system attempted to access pageable
memory using a kernel process IRQL that was too high. Drivers that have used
improper addresses typically cause this error.
Possible Resolutions:
• Stop 0xD1 messages can occur after installing faulty drivers or system
services. If a driver is listed by name, disable, remove, or roll back that
driver to confirm that this resolves the error. If so, contact the manufacturer
about a possible update. Using updated software is especially important for
backup programs, multimedia applications, antivirus scanners, DVD playback, and
CD mastering tools.
Let me know if you need anything else.
