Can anyone advise me where to look in order to trace this problem further?
The load idle seems a bit high for just sitting there and doing nothing.
Can you run 'powertop' while in text mode (no X running) and see what is showing up as being the thing that is waking the processor up the most?
Hopefully that tool will work, but I don't know, as that is a very old processor.
Many thanks for your suggestion. Powertop shows that there are about 250 interrupt events per second, 95%+ being "extra timer interrupts". The answer is about the same whether or not I enable ACPI in the kernel, except for some not wholly credible figures are added (C3 state 159% for example) if I enable ACPI. I can't find any explicit definition of "extra timer interrupts" on the powertop web site, do they mean anything to you? -- Roger Hayter -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
