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
