This same drive works fine when plugged into the 5 disk backplane, or plugged in to a different make/model of adaptor (one with no chips) I have 7 of these adaptors and all of them exhibit this same problem with any SCA drive I plug into them. I have test these adaptors under both -CURRENT and -STABLE on adaptec 2940 U2W's. This setup does cause panics under -STABLE at boot, I haven't tested under -CURRENT. I don't happen to have the output of a panic handy if someone needs this let me know and I'll track one down. If any further information is needed please let me know and I'll be happy to provide what ever I can.
