High DPC Latency and frequent Interrupts

[dkarocks]

I am getting frequent interrupts which freezes the whole system for a second. I am attaching some screenshots from Latency Monitor which might be useful.

I have also made a xperf trace too using this command:

xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS+POWER -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular

Here is the link to the trace file Dropbox - CPU.zip

Can someone have a look at this trace file and suggest what could be the problem?
I would be glad to provide any additional info if needed..

Thanks
