Ragnar (nice name reminds me of my THOR readings when very young :)),
thank you. Are you suggesting that I try with 2.6.10 and APM ?
I have tried 2.6.9 and APM and 2.6.10 and 1.6.10-rc3-mm1 with ACPI and I
could try 2.6.9 with ACPI (maybe I did but do not remember the outcome)
or the 2.6.10 with APM ...
Let me have your ideas on this please.
Thank you very much,
Bob
