Rick,
There were no resource hogs in "ps ax" or "top".
It wasn't "updatedb". "DAILY_UPDATE" was no. I have been booting the
machine at least once a day
since I installed on January 16. BTW, I love "slocate".
I turned off acpid first by stopping the service; things improved
dramatically and instantly.
Then I chkconfig'd it off.
I want to boot with "noacpi". Where do I put that?
Thanks,
Brenda
