Those number are in hex, so "811" is major 8, minor 17 which is (or should be) /dev/sdb1. Look earlier in the boot up sequence, where the aic79xx driver is loaded and scans for devices. It should say that it has attached /dev/sdb . You may need a later version of that driver. Visit: http://people.FreeBSD.org/~gibbs/linux
