 pci_conf_write() is not in the stack trace?  Please capture and send
 the entire stack trace (type 'bt' at the db{0}> prompt) if you can.
 Please send the dmesg you get when you apply your workaround, also.
 
 Can you examine the netbsd.gdb file with gdb for me?  The gdb command
 'l *(pccbb_chipinit+0x3b5)' will tell you a line number in pccbb_chipinit.
 I would like to know that line number.
