It's a completely separete issue, as we are talking about NetBSD-current,
not 1.6.

The source code may help you to get further information:-)

Captured from sys/dev/ic/i82557.c
	 * Systems based on the ICH2/ICH2-M chip from Intel, as well
	 * as some i82559 designs, have a defect where the chip can
	 * cause a PCI protocol violation if it receives a CU_RESUME
	 * command when it is entering the IDLE state.
	 * The work-around is to disable Dynamic Standby Mode, so that
	 * the chip never deasserts #CLKRUN, and always remains in the
	 * active state.
	 * Unfortunately, the only way to disable Dynamic Standby is
	 * to frob an EEPROM setting and reboot (the EEPROM setting
	 * is only consulted when the PCI bus comes out of reset).
	 * See Intel 82801BA/82801BAM Specification Update, Errata #30.
