CPU Maxed - Hardware Interrupts Possible Culprit

Thread needs solution

I am using a version of Acronis Backup that came with my Seagate BlackArmor 2TB network storage. I have it installed on 2 XP machines both using GB network cards.

On my MAIN machine (XP Pro) all is well and backups proceed at a comfortable rate.

On the 2nd machine (XP Home) it's a different story. When the scheduled backup begins the CPU use goes to 100% or close to that. When the backup is completed the CPU use returns to normal.

Further examination of where all the cycles are going with "Process Explorer" indicates that 85 to 90% of the use is with "Hardware Interrupts".

I have no further details on what these "Hardware Interrupts" might be? Any thoughts out there? Could this possibly be a driver conflict issue?

Thoughts appreciated - thanks.
