Hi Sam, there seems to be a bug in the linux kernel aoe driver version 47q. This version has problems with the calculation of major and minor numbers. We export a device with major number 2 and minor number 16 (dec) via ggaoed (shelf=2; slot=16). But the aoe driver tries to read e3.0 instead of e2.16. This is validated by using minor = 17. Then aoe tries to read e3.1 instead of e2.17. In the specs there are 8 bits used for the minor number so 255 as the max minor number should be allowed.
