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 lspci: 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 12) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) 00:16.2 IDE interface: Intel Corporation 5 Series/3400 Series Chipset PT IDER Controller (rev 06) 00:16.3 Serial controller: Intel Corporation 5 Series/3400 Series Chipset KT Controller (rev 06) 00:19.0 Ethernet controller: Intel Corporation 82578DC Gigabit Network Connection (rev 06) 00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) 00:1d.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a6) 00:1f.0 ISA bridge: Intel Corporation 5 Series Chipset LPC Interface Controller (rev 06) 00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 6 port SATA AHCI Controller (rev 06) 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller (rev 06) Has anyone else seen similar?

I would set up remote syslogging from the unit under test, and see exercise (through keyed ssh access) that unit under test on a scripted basis, to see if it dies off if left alone, or if other clues appear in that remote syslog -- Russ herrold
