I can work with this.
It seems to be working.
After correcting the RTC, now I get a more or less good boot time:
[root@nixos-riscv:~]# systemd-analyze
Startup finished in 4min 49.469s (kernel) + 10min 48.260s (userspace) = 15min 37.729s
multi-user.target reached after 10min 48.024s in userspace.
Still, udevd is killing the CPU:
[root@nixos-riscv:~]# vmstat 1
