Bug#991951: debian-installer: Text installer sporadically hangs when using 512 - 1024 MB of memory.

[Witold Baryluk <witold.baryluk@gmail.com>]

Package: debian-installer
Severity: important

https://www.debian.org/releases/bullseye//amd64/ch03s04.en.html says this should be supported.

But when using 512 MB of memory in text mode (which triggers low memory mode),
or even 1024 MB of memory, makes it be stuck.

Using multi-arch image for testing.

wget https://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/multi-arch/iso-cd/debian-testing-amd64-i386-netinst.iso

qemu-system-x86_64 --enable-kvm -cdrom debian-testing-amd64-i386-netinst.iso -m 1024

Select "Install" (text installer, not graphical one).

Select defaults (or other) for language, location and keyboard.

Let it load installer components.

It will sometimes load, but more often than not, if you start again from
scratch, it will hang somewhere forever. For my the failure ratio is
about 90%.

PS. Curiously, Graphical installer works just fine with 1024 MB of memory.
