This might not be the right place to ask this, but I am at wits end. I have a Gigabyte K8NS pro and AMD Athlon 64 Socket 754 3000+ Everything works ok except ,my kernel cpu utilisation hovers at minimum 30% sometimes even peaking at 90% while the process list shows the system is 99% idle !!!!!! Bios Version is F8, going to F9 later hope it helps. Any clues will be appreciated.
Fresh install, no internet connection and no userland processes using any cyles. All activity is shown as kernel time, i suspect that its a 3rd party kernel mode driver for the RAID or other subsystem.
