Ah well, at least that means it's not just some lingering error condition
that triggers as soon as error reporting is enabled (or that our error
reset doesn't actually work). I guess some more debug output is needed to
determine what's going on exactly.
In either case the error condition seems to come from the PCIe port that
has the wired ethernet controller attached (PCI device 28 function 5 with
secondary bus 8). From the data available alone it doesn't really look any
different from the other PCIe ports...
That reminds me though that the error condition clearing only every uses
kprintf to output the data to the kernel debugger. What you could do when
the NMI kicks in is execute the "pcistatus" KDL command, which should then
list any present error conditions before trying to clear them. If you
could attach that output (you can simply continue after executing that
command) as well, that might give some clue.
