This info applies to Fedora Core (and may apply to other Linux distros). My problem occured when upgrading a FC3 system to FC5 and the acpi drivers apparently changed. The working acpi setting from FC3 made a nasty mess of FC5. You see this error on the console: transmit timed out status 0003 PHY status 786d resetting Ethernet appears to be there, but no packets reach the interface. You can tell this by looking at the output of ifconfig. There will be no rx or tx packets. Also, the AGP section of dmesg will be weird and full of zeros. In file /boot/grub/menu.lst Remove any acpi options from the kernel line, and add this: nolapic noapic acpi=off
