Yea, I think that's all it is. Once I did less work, the problem went away, although I still get a lot of warnings from ISP about pretty much the same thing (so maybe I'm *close* to the line). Also, I recently booted up 6.1-RELEASE cd with two qlogic 2312's, installed, and booted up. After updating to -STABLE, and rebooting, I either would hang forever (literally days went by), or I resulted in a panic (when ispfw was loaded). Once I plugged the hba's into something, the issues went away. Only when they were totally disconnected did I have any issue. Let me know if you need more info/testing.
