Systems based on the ICH2/ICH2-M chip from Intel have a defect where
the chip can cause a PCI protocol violation in under certain scenarios.
The workaround is to rewrite the EEPROM to disable Dynamic Standby Mode.
Once the EEPROM is rewritten, the system needs to be rebooted in order
to pick up the new settings.
This has been tested on several ICH2/ICH2-M systems, found in 815E based
boards, and usually identified by the presence of the 82562 ET/EM PHY.
Thanks to: Mike Tansca, Paul Saab for samples of the problematic boards.
