cat /proc/pci and NCR 810 SCSI parity error

using 2.1.122 with CONFIG_PCI_OLD_PROC=y I get a SCSI parity error
when running

# od -tx1 -Ax /proc/bus/pci/00/01.0
# cat /proc/pci

where /proc/bus/pci/00/01.0 is the NCR810 (kernel messages below)

any idea what's wrong with accessing /proc/bus/pci/00/01.0 and `cat /proc/pci'
and/or 2.1.122 ?
