re: 4.99.51 kernel crashes while detecting a PCI card

[matthew green <mrg%eterna.com.au@localhost>]

   when I tried out a 4.99.51 kernel on my ULTRA60 to check whether
   PR port-sparc64/3034 is fixed it paniced when it detected the PCI-X card:
   
   bge0 at pci1 dev 1 function 0: Broadcom BCM5701 Gigabit Ethernet
   cpu0: data fault: pc=12eac80 addr=0

null pointer access.

this seem very strange, and i do not think it has to do with
pci_conf_read().


   kernel trap 30: data access exception
   Stopped in pid 0.1 (system) at  netbsd:pci_conf_read:   ldx             [%o0

can you instrument this function to see where it dies?

thanks.
