Also an obsevrastion: cpu load seems to be spread equally between all available cores, according to the top command on the host. This was in the Interrupt CPU Usage Table.In the DCP CPU Usage table, the big boy was a very similar process; Module "Unknown", and function "0xfffffa80076e10a0".Do you have any insight?

VBox log file from test machine with high cpu usage from interrupts.

The same VM disk image runs fine on other virtualization platforms (XenServer 6.5, VMware ESXi 5.0), with CPU usage from interrupts being virtually zero.

yes i agree ... This is an amazing find. After updates, idle CPU is around 10-20% for each VM. Windows 7 Hardware Interrupts High Cpu Usage drop-outs due to high latency, something is off.

I'm having a similar if not identical problem.

Therefore the driver for the AC adaptor will have a reasonably medium high interrupt since you don't want to overclock the CPU on batteries.

Now run the xperf commands again and look if you see the real driver.Ok, I hope, this helps you to determine which driver is causing high DPC, interrupt usage and spikes I saw that message on Windows 8 compatibility, but didn't notice any unusual readings on my Windows 10 device (no suspicious system interrupts, either). Thanks a lot man.......and now I can buy myself a guitar.......i thought i had to buy a new laptop until i found the solution u gave me here! it solved my problem.

Why is it even an option? 10/21/2007 7:39 PM Jim Holmes said... @NFrickleton: It's an option because older sytems needed that slow IO mode. I discovered when I enable hibernate the problem went away, but that uses up 10 GB of drive space and I never use hibernate mode. I've struggled for over a day thinking it might be USB issues, hard disk problems.....did what you said here and Shazam, PC back to normal!
