hello all,
I'm hoping someone can give me a hand with this. I have a suspicion as
to what is causing this, but I don't want to "taint" any replies I get.
If any of knowledgeable folks out there could help me out, offer
possible areas to look into, better places to contact, or anything that
could possibly be helpful, I would really, really appreciate it.
thanks in advance,
Nick
Info follows:
System:

HP Proliant DL140

FreeBSD 5.2-CURRENT #0 standard kernel

Problem Description:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
System becomes unresponsive and "hangs". System does not respond to
keyboard, network or any other type of input.
Error Message:

Also, in order for the machine to detect it's broadcom 5700 network
cards, I had to the line
acpi_load="no"
to my /boot/loader.conf. Upon reboot the network cards show up in an
ifconfig and work perfectly.

This isn't the exact same error, but it's the closest thing I could find
to my error:
http://lists.freebsd.org/pipermail/freebsd-current/2004-March/022633.html
This error is also pretty close, but not the same thing:

Thanks for taking the time to read this.
