Well, it worked around it. > Any ideas? I am happy to provide any details you may need. I'd guess that this is another ACPI issue like the one I reported a couple of weeks back. In my case, it was slow, but I didn't lose any keystrokes. What happens when you ping another system? I found that the ping time was normal (in the order of 1 µs), but it repeated only every 3 seconds. When I unloaded ACPI, things worked normally. I'm following this up to the ACPI list with a reminder that my message has been there for 2 weeks. How do I localize the problem? Greg -- See complete headers for address and phone numbers
