Mount root warning message

I see the following warning message during the boot sequence of any FreeBSD machine on stock hardware:

Code:
acd0: FAILURE: READ_BIG ILLEGAL REQUEST asc=0x64 ascq=0x00
Trying to mount root from ufs:/dev/ad6s1

What does this mean and is it really a warning or something that should be fixed?

Thank you in advance

Set this

hint.apic.0.disabled="1"

in /boot/device.hints and the error will disappear.This is a common error nothing to worry about.
