Looks like this has been adresseed in current, or at least there is something written about it. > CVS log for src/sys/dev/aic7xxx/ahc_eisa.c 1.19 Mon Jan 22 21:03:46 2001 UTC by gibbs ahc_eisa.c: Initialize rid to 0. This doesn't seem to make any difference (the driver doesn't care what rid it gets and no-one seems to check rid's value), but follows standard conventions. Pass in our device_t to ahc_alloc(). We now use device_T softc storage, so passing NULL results in a panic. Set the unit number in our softc so that the driver core can retrieve it. My DDB traceback, which i have not handy right now has something with ahc_alloc and softc in it. I can reproduce this, if someone needs the traceback. I haven't had the time to investigate any further. > Help! (Please) 4.2-RELEASE works, at least for me, without any problem.
