Thanks, I understand now.

Good that you upgraded, because Tim would have had to do it otherwise.

At that stage of my diagnosis of #12757 I had excluded Open Firmware
as cause; it has stopped running once the Linux kernel starts.

So it should not have mattered what firmware was used.  But to keep
the number of variables down, I wrote Q2F19 in the call for testing

The wireless adapter firmware version may have been relevant, but it
had not changed for a very long time, and is included in the operating
system build, so it didn't really matter.
