BSOD with Windows 7, HP Eitebook 2560p


Recently I've begun having BSODs on my HP Elitebook 2560p for no apparent reason. Minidump available at

Any clue about where to look at? Thank you very much



Hi Joaquín,

The attached DMP file is of the DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) bug check.

This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.

A driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high. This bug check is usually caused by drivers that have used improper addresses.

If we take a look at the call stack:

0: kd> knL
 # Child-SP          RetAddr           Call Site
00 fffff800`00b9c158 fffff800`03c7a1e9 nt!KeBugCheckEx
01 fffff800`00b9c160 fffff800`03c78e60 nt!KiBugCheckDispatch+0x69
02 fffff800`00b9c2a0 fffff880`058babfe nt!KiPageFault+0x260
03 fffff800`00b9c430 00000000`00000000 NETwNs64+0x21abfe

We can see a NETwNs64.sys (Intel(R) Wireless WiFi Link 5000 Series Adapter Driver for Windows 7)

call into a page fault, and then the bugcheck.

0: kd> !sysinfo machineid
sysinfo: could not find necessary interfaces.
sysinfo: note that mssmbios.sys must be loaded (XPSP2+).

I cannot seem to run the extension to get your computer model, so please visit your manufacturers website and be 100% sure your network drivers are up to date. You can also try Intel's site directly if not -
