1) setenv fcode-debug? true then restart
2) false to check-visible then try the .time-stamps command again.
Probably the first is preferable since you only have to do it once (unless you zap the pram).
probe-all does the following:
push-state
probe-pci
probe-ext-mac-io
probe-usb
probe-fw
finish-device-tree
pop-state
I suppose you can try probe-pci instead of probe-all. In that case, maybe remove banner so that the normal boot process will do probe-all. It should be smart enough not to repeat the probe-pci part again but I'm not sure.
In either case, you may want to use a catch so that if it fails, the rest of the nvramrc script is executed.
['] probe-pci catch if ." exception:" . . cr then
