in both cases the crash happened at exactly the same place in the same
upgrade
I discovered a few more points: That upgrade problem is not unique to
me. In most cases people who did that upgrade and had a problem suffered
a complete loss of the /boot/firmware directory.
I haven't got chapter and verse but the common factor seems to be
upgrading from a previous version to the Dec 2023 version using apt-get
upgrade..
I discovered why my December 2023 version didn't install, as well. It
was corrupted somehow. It wouldn't mount. I re-downloaded it,
re-installed it and that finally did boot, but there were strange file
and read errors when I attached the *second* disk to the system. But a
reboot cured *that*.
The system upgraded perfectly well once the new OS image was installed.
Perhaps the power supply is inadequate?
I don't know
At the moment I have rebuilt to about the same point the development
system was when it bricked
I've checked the disks with smartctl and there are no errors logged.
So the problem would seem to be with the pi itself or the OS. or some
other part of the hardware.
