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?
