Before changing anything around, try disabling all synchronous and wide negotiation to the tape drive and see if it works. If it does, then let me know what your CPU at home and at the office are as there may be some kind of CPU speed related timing bug lurking in here. There may also be a generic issue where certain cards simply are broken in regard to REQINIT handling (kind of a partial latent defect type thing, like the CPU I once had that would run linux 24 hours a day 7 days a week without a problem, but the first time I tried to run 16 bit apps on it, it would crash presumeably because some of the 16 bit microcode had gotten fried when it overheated). -- Doug Ledford Opinions expressed are my own, but they should be everybody's.
