As far as I can see from the debugger, XP sp 0 will bugcheck on calling
MmMapIoSpace with the folwoing values for p1
0x73 , 0x83 and 0x84
Latest Windbg help file further documents p1 equal to 0x87 and 0x88 ,
signaling cache conflicts. But I found no evidence that the kernel will
issue verifier bugchecks with those values.
My question is : are those a new addition to XP sp1+ *ONLY* , or I failed
to find them ? I analyzed VerfierMapIoSpace() function, which is the
logical place for those checks to be found.
Thx , Dan
what does !analyze -v say?

Im not concerned here with analyzing a bugcheck. I only analyzed the
verifier version of MmMapIoSpace() API internals as a result of some
questions on this list.
