The reason is printed before because mem_parity_error is treated as
something like unknown reason. And iochk_error is treated as known
reason and will not print the reason byte. Please the check the original
code.

But now we treat pci_serr_error (renamed from mem_parity_error) as known
reason. So it is not necessary to print the reason byte. I suggest to
print the reason byte only if (!(reason & 0xc0) && reason), where the
reason is really unknown.
