Did you get this from the messages file by cut 'n paste or type this

from sys/dev/fxp/if_fxp.c:
/*
* Enable workarounds for certain chip revision deficiencies.
*
* Systems based on the ICH2/ICH2-M chip from Intel, and possibly
* some systems based a normal 82559 design, 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
* workaround is to disable Dynamic Standby Mode, so the chip never
* deasserts CLKRUN#, and always remains in an active state.
*
* See Intel 82801BA/82801BAM Specification Update, Errata #30.
