Version 1.55 of /sys/i386/isa/pcibus.c causes an IBM NetFinity 7000 (and
possibly other similar boards?) to find multiple copies of the GX chip.
Reverting to 1.54 cures the problem, but obviously doesn't address the
problem of the Dell machines it was trying to fix. :)
The problem doesn't immediately leap out at me, but the following section
seems suspect due to the 7 extra busses:
@@ -425,14 +434,20 @@ static void
nexus_pcib_identify(driver_t *driver, device_t parent)
{
pcicfgregs probe;
+ u_int8_t hdrtype;
int found = 0;
+ int pcifunchigh;
if (pci_cfgopen() == 0)
return;
probe.hose = 0;
probe.bus = 0;
for (probe.slot = 0; probe.slot <= PCI_SLOTMAX; probe.slot++) {

for (probe.func = 0;
probe.func <= pcifunchigh;
probe.func++) {
This one confused me for some time as I went into the BIOS to twiddle
options on this machine for the first time on the same reboot that I
happened to frist boot a kernel made after the 1.55 commit.
It took quite a while to finally suspect a source change rather than a
misconfiguration, especially since this machine was new with the
installation of 20000208-SNAP, and I had done several make worlds on it in
the preceding 36 hours or so, and all the kernels booted fine. A quick
test of the original GENERIC finally pointed the right way. :)
A sample bungled dmesg and one corrected by backing out 1.55 follow:
