thanks

Hello,

This bug is no longer present in kernels shipped in Debian stable /
testing / unstable. Do note, though, that the Raspberry Pi 2 is sold
with 1GB RAM only and cannot be upgraded, and thus has no use for
LPAE, we have used only regular linux-image-armmp kernels (and have no
reason to suppose -lpae is needed).

At the time of my bug report, I had not tested it yet. I checked right
now, downloading an image from raspi.debian.net, and installing the
-lpae kernel, I can confirm it boots correctly all the way to:

    root@rpi2-20200910:~# uname -a
    Linux rpi2-20200910 4.19.0-10-armmp-lpae #1 SMP Debian 4.19.132-1 (2020-07-24) armv7l GNU/Linux

OK, I'm happy to have understood this correctly :-)
