Good afternoon,
(f-28) I closed this about a year and a half ago because a bug was already filed regarding the issue. For the past few days, both before and after doing my latest weekly patches, I noticed that those "ACPI Error" messages no longer show up while the workstation is booting. So I'm promoting this thread from "CLOSED" to "SOLVED". My thanks to the people fixed the problem. I hope it's fixed for everyone else who experienced the problem.
Bill.
