Sharp UM32W powers off randomly

Hello Everyone,

I've been running FreeBSD 5.3-RELEASE on my Sharp Actius UM32W for a month now. I'm still new to FreeBSD so I'm doing a lot of learning on the fly. 

One issue I've run into is that the unit will randomly power off on its own. It has happened under load, while compiling, and also when the system is sitting idle. It's spiratic and unpredictable.

Since I'm still very new to FreeBSD I'm uncertain whether it's something I've configured incorrectly or if it's a problem that is beyond the scope of this mailing list. The cooling fans turn on when the system is under load so it seems that ACPI is functioning correctly. I'm using the default GENERIC kernel.

Can anyone point me in the right direction so I can dissect this issue and see where I've gone wrong? 

Thanks,

 - jstn
