(...)
installed Debian GNU/Hurd using the 2023 release CD image on a laptop with
512 MB of RAM. This is a HP Compaq nx6110. The installer went into "Low memory
mode" (...)
Unfortunately, my computer (512 MB) stops at the kernel loading and no installation program is launched.
My computer boots with a kernel up to 2022.12.27. Subsequent kernels do not work.
Could you repeat and check your installation now?
