This is meant as an emergency measure (thus no "Fixes"), and should be
properly addressed at some point.
hmm, the R7800 must have some crazy bootargs-overrides when these
impact sysupgrade as well. Let's hope there isn't an issue with
the platform.sh + asrock.sh changes.
@hannu: can you please post your R7800's /proc/device-tree/chosen/ files
(name + content)
for reference?
Cheers

There aren't that many files (like Adrian already said).
This is the contents in r15359-2160a9d597 with that offending kernel symbol
disabled:
root@router1:~# ls -l /proc/device-tree/chosen/
-r--r--r-- 1 root root 1 Dec 28 17:05 bootargs
-r--r--r-- 1 root root 25 Dec 28 17:05 bootloader-args
-r--r--r-- 1 root root 7 Dec 28 17:05 name
-r--r--r-- 1 root root 17 Dec 28 17:05 stdout-path
root@router1:~# cat /proc/device-tree/chosen/bootargs
root@router1:~# cat /proc/device-tree/chosen/bootloader-args
console=ttyHSL1,115200n8
root@router1:~# cat /proc/device-tree/chosen/name
chosen
root@router1:~# cat /proc/device-tree/chosen/stdout-path
serial0:115200n8
Also the cmdline in /proc is empty
root@router1:~# cat /proc/cmdline
Note that in the "normal" situation, the bootlog says that the
bootloader-args get ignored:
[ 0.000000] Bootloader command line (ignored): console=ttyHSL1,115200n8
Apparently the introduction and enabling of CONFIG_CMDLINE_OVERRIDE causes
that faulty(?) line from bootloader-args to get applied, while it gets
normally ignored.
No detailed idea why sysupgrade failed, but I suspect that it may somehow tie
to the console tty being wrong.
I got first notified about that sysupgrade problem in forum discussion, and
then yesterday I tested it by myself.
A few messages at https://forum.openwrt.org/t/build-for-netgear-r7800/316/2753
I would need to reflash a faulty build to see the problem again more
closely... (But that would only make sense if you have good ideas how/what
to debug without serial console)
