Sorry about that, Carsten. Notwithstanding, no dump file is being generated.

I continue to get those sefaults (from today's dmesg output)

Probably my next task is to refresh EFL/E by generating another build
for Debian Buster backports GCC8 for AMD64...

notwithstanding, I have experienced stability issues, as well, in the
most recently build of EFL/E for Debian Bullseye GCC10 for AMD64;
i.e., sometimes when building a reiser4 -enabled kernel(s) -- a task
that takes approximately couple of hours in this oldie Intel machine
-- I will return and find an XDM login screen. Apparently EFL/E
environment crashes and kicks me out (no dump file, either). I do not
lose my partial kernel build due to the atomicity feature in reiser4,
notwithstanding, it is annoying when it occurs.

Ever since I switched ot E, I do not use any other window manager
environment so I would not know if those bloated like GNOME and/or KDE
are as unstable. Probably I will try WindowMaker in Bullseye to find
out if behaviour is similar/else/not.

 uname -a
Linux huitzilopochtli 5.10.0-5+reiser4.0.2-amd64 #1 SMP Debian
5.10.26-2+reiser4.0.2 (2021-03-27) x86_64 GNU/Linux

Best Professional Regards.

P.S. I could build my kernels in the cloud -- in half-an-hour or so --
by using rented computing power
< https://metztli.blog/amatl/reiser-nahui/bullseye >
so as not to stress EFL/E locally ;) but after a while it becomes
somewhat expensive.
