Hello list,

did anyone (Jason ???) have time to look into the ahb /Jensenio/EiSA

I had tracked down the problem on not getting a valid return on the irq
in the 1742 driver irq routine:

 if ((bus_space_read_1(iot, ioh, G2STAT) & G2STAT_INT_PEND) == 0)

                return 0;
        /* this point is never reached ! */

always receives a 0 status and thus always returns without doing
anything or clearing the interrupt. I have the Jensen manual but I
really do not know where to start looking for the problem (Problems with
the EISA bus code ???).

All pointers appreciated !
