Yeah, wierd....I must be misremembering then.

In any case, the HPMC occurs on the first none-zero numbered Sym2 device:
sym53c8xx 0000:00:01.0: enabling device (0000 -> 0003)  is OK
sym53c8xx 0000:00:01.1: enabling device (0146 -> 0147)  is OK
sym53c8xx 0000:00:02.0: enabling device (0000 -> 0003)  is OK
sym53c8xx 0000:00:02.1: enabling device (0000 -> 0003)  is OK
sym53c8xx 0000:30:00.0: enabling device (0000 -> 0003)  seems to be OK
sym53c8xx 0000:38:00.0: enabling device (0000 -> 0003) HPMCs?

The second cards seems to be the culprit though there are
two add-on cards in the machine (I was expecting both to
fail in similar ways).

I saw you included the PIM dump with a later console capture
but I won't have time this week to look at it. :(
This PIM dump should confirm if we had problems accessing MMIO
space and which device (should) owns that space.

thanks,
