Just to recap, I flashed the kernel and the rootfs using the live CD.
Then as mentioned above wrote 4kb of zeros to 0x2adc8000 and 0x2a5c8000.

The behavior did not change, before and after the forcing a reformat of the user areas (/var/local and /mnt/us).

Which probably means that was what (reformatting the user areas) it was doing before the above work.

It MAY (or may not) be making progress.

The flash chip's controller has to try an erase/re-program cycle on a bad block to discover that it is bad and replace it with a spare.
So keep it powered by an external charger and let it cycle.

Perhaps for days - depends on the extent of the flash chip's damage.
(The 4 hours+ Kubrick time also indicates trying to recover from flash chip damage.)

Knocking on wood, crossing your fingers, <insert favorite security belief here> might help.
