Why is it every so often the process Kupdated runs for a few seconds and takes 99% CPU usage?
are you using DMA and hdparm on your hard-disk? most likely the kupdated is writing out unflushed buffers and is using lots of cpu to do the disk writes. What happens if you do lots of disk I/O?
Um yes, which brings me on to another question, how do I make hdparm run everytime I boot up? ATM I run it by hand. The problem with Kupdated is caused mainly by heavy disk activity, which also knocks out the network card for some strange reason!
Stick it in a script put the script in /etc/init.d/ and link to it from /etc/rcS.d/S99hdparm > /etc/init.d/nameofyourscript and it will get run once at every boot including single user so beware....
