 Hmm, it looks there is some problem around PIC initialization.
 
 Anyway, there is a report that ahb(4) works on AlphaServer
 http://mail-index.netbsd.org/port-alpha/2007/04/11/0011.html
 (no device is connected to ahb(4) though)
 so this may be a Jensen specific problem.
 
 There is no reference code about the interrupt controller on Jensen
 so I have no idea of proper solutions, but could you try this one
 (with both "a" and "n" flags)?
