In a possibly not-quite-matching manual:

   cbf0 = HPMC occurred
   500b = bus timeout (slot 0, bus 0)
   cbf5 = IVA+32 was equal to 0
   cbfc = branch to os HPMC failed

CR19 (IIR) = e601181 = LDWAS    0(0,19),1

So, looks like an absolute load was being done, using R19 as the address:

   R19 = fffffffffff80810

The "System Responder Address", whatever that is, is 0x000000fffff80810
which is suspciciously similar to what's in R19.
