The trick now is to figure out who is passing a bogus value to bus_dmamap_load. The value of buf_len (0xfaae8000) looks suspicious. Since I hve essentially the same h/w (except for the symbios card) in a PC164 that runs 4.2 just fine, I would suspect the sym driver. But needs to happen is some better debugging for this. I take it that you aren't really running on this h/w yet (i.e, you haven't been able to install)? -matt On Thu, 4 Jan 2001, Yoriaki FUJIMORI wrote: > > Thank you for your responce. > I use one noname DEC-based NIC.
