Windows 10: High DPC and IRQ CPU from Ethernet Driver / Windows Network Stack Causing computer stalling.

thelenko · Nov 21, 2019

Hi,

I am getting periodic temporary freezing (computer becomes unresponsive for up to a minute) while browsing (using any browser).

I ran windows performance analyzer and what jumped out as suspicious is a sudden big spike in DPC and IRQ cpu usage. The stack trace went through various network stack (ndis.sys, tcpip.sys) leading down to the ethernet driver (e1d68x64.sys).

I have tried re-installing Ethernet drivers and doing a complete Windows 10 refresh without success.

How do I further diagnose/repair this, or get the right set of eyes on a potential bug?

Thanks

:)

Very high DPC latency on Win10 in ndis.sys

there was a post with the same problem:

ndis.sys- High DPC latenecy / High DPC CPU usage

which was fixed by disabling power management for the network adapter.

Something causing high DPC (User process and at times a driver)

Have noticed that i seem to get sky high DPC at soem occasions.
I haven't really suffered from anything before, but recently i had some audio glitches which i haven't been able to reproduce.
As i have overclocked recently with offset voltage i though that might be the cause, however as said i cannot reproduce the audio glitch, might have been something interfering (it was huge glitch though, though it was gonna crash, happened like 2-3 times).

Anyhow, i have tried non-OC as well, but looking at my DPC it seems that it always gets high for some reason.

Especially the User process. Driver has become high, but hasn't confirmed that without OC (it's a bit rarer, and i think it's USB driver, though no idea why).

This is with no overclock, just the default BIOS settings, with only some stuff disabled (USB 3.0, etc, and HDD set to AHCI).

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
____________________________________________________________________________________________________ _____
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Average measured interrupt to process latency (µs): 3.868848

REPORTED HARD PAGEFAULTS
____________________________________________________________________________________________________ _____
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: chrome.exe

Total number of hard pagefaults 15248
Hard pagefault count of hardest hit process: 3996
Highest hard pagefault resolution time (µs): 1476851.217159

DPC HELP NEEDED BADLY IRQ Less than equal

i have major dpc issues. the drivers causing it are MS ACHI StorPort Miniport driver and scsi class system dll.

i need help

i get an error message blue screen saying irq less than equal every once and a while now.

thanks ahead of time
