Hello,

I recently had some problems with my ASUS P5A motherboard (K6-II 350) on 
FreeBSD 5.2-RELEASE.
In fact, I had GENERIC kernel installed and ACPI activated.

First problem:
Time flow was incorrect. In fact, 1 second meaned 0.5 second for FreeBSD.
Each minute I tested a ntpdate and there was 76 seconds difference.
When I rebooted and check in BIOS, time was correct and flowed independently.

Second problem:
on my LAN there is a gateway on FreeBSD 4.9-STABLE that manages the internet 
connection.
When I traceroute/ping anything on the net from my PC under 5.2, there was 120 
ms latency between my gateway and my first hop (provider LNS).
- From any other PC of my LAN, there was normal 60 ms latency.
I changed network cards of PC under 5.2, changed RJ45 connector... nothing 
changed.

I decided on boot to disactivate ACPI by setting hint.acpi.0.disabled to 1.
No problem anymore, normal time flowing, normal ping.
