Tape drive resets the server!

I don't mean that the kernel panics or anything; I mean that within a second or two I'm looking at a POST screen. I'd been having this problem for a while, but recently upgraded literally every other piece of hardware on the system. The card and drive were the *only* components carried over to the new system, and I even swapped out the card for a duplicate I had stored away. Is it possible that the drive itself is triggering the reset? I'd find that a little unlikely, but am certainly not an expert on the matter. Alternatively, has anyone had that sort of problem with drives attached to that card? -- Kirk Strauser
