Those addresses that begin 9b640000 (including the fault address) look
very strange. The low 32-bits look like a valid physical address in the
PCI space but the top bits definitely don't look right (unless the
kernel's playing tricks with unused address bits; I'll have to check the
RM523x data sheet to see if they have any effect). Have any of the MIPs
experts commented ?
