Hi.

I was able to build linux-5.5 and run it on N900 with no problems.
Even WiFi works, mmc0 is in place too. It seems you're doing something
wrong.

Were you able to build linux-5.1 with your scripts and run it on the
phone? I mean the pure linux-5.1 without configs and changes done
in https://github.com/maemo-leste/n9xx-linux.

BTW, I didn't find STACKPROTECTOR_PER_TASK option to be enabled in
omap2plus_defconfig.
