I have installed CentOS 5.5 (2.6.18-194.17.1.el5PAE) on a number of Acer 
Veriton X498G desktop computers.  They seem to randomly hang when nobody 
is logged in at the console, i.e. I notice a hanged computer but have 
not heard complaints about computers hanging while a user was at the 
keyboard.

The symptoms are:
	Blank screen.
	Power LED on.
	Network LED blinking.
	No response to keyboard or mouse.
	No response to ping.
	Arp request from computer on same subnet gets "incomplete" for MAC address.
	Cannot ssh into computer, "no route to host" error message.
	
The power management BIOS settings are set to default:
	ACPI aware OS			yes
	ACPI suspend mode		S3
	Deep power off mode		enabled
	Power on RTC alarm		disabled
	Power on PCIE devices		enabled
	Power on modem ring		enabled
