Package: debian-installer
Severity: serious
Justification: graphical installer regression

Hi,

Ever since we switched from linux 4.15 to 4.16, the graphical installer
gets a black screen. Comparing Xorg logs, everything is exactly the same
except for the kernel version and timestamps. syslog has extra lines
about random stuff:

    May 12 02:25:01 init: starting pid 169, tty '': '/sbin/reopen-console /sbin/debian-installer'
    May 12 02:25:01 init: starting pid 172, tty '/dev/tty4': '/usr/bin/tail -f /var/log/syslog'
    May 12 02:25:02 init: process '/sbin/reopen-console /sbin/debian-installer' (pid 169) exited. Scheduling for restart.
    May 12 02:25:02 init: starting pid 201, tty '': '/sbin/reopen-console /sbin/debian-installer'

                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    May 12 02:25:19 init: starting pid 170, tty '/dev/tty2': '-/bin/sh'

    May 12 02:25:24 kernel: [   25.303708] random: crng init done

After a while, this happens:               ^^^^^^^^^^^^^^^^^^^^^^

Once that has happened (so after 20+ seconds), the screen comes up
properly without any intervention. I think I've seen reports on
#debian-kernel about boot stuff like plymouth/cryptsetup having issues
gathering entropy at the early stages of the boot sequence, but I'm not
sure that's a regression in the kernel, and/or something that should be
dealt with from within cdebconf.

That's why I'm filing this bug report for the time being, feel free to
mention actual bug reports on the kernel side, and to suggest ways to go
from here (I haven't followed that quite closely).

I've X-D-Cc'd debian-kernel@ as their input is more than welcome.

Interestingly, the text installer is working just fine so I guess it's
something frontend-specific (some X11 fun?), but I won't dig into that
right away.


Cheers,

Changes:

 .
   [ Cyril Brulebois ]
   * Bump Linux kernel ABI from 4.13.0-1 to 4.16.0-2
   * Replace c_rehash with openssl rehash (Closes: #895074). That should only
     affect builds with SSL_CERTS enabled; regular HTTPS support comes from
     ca-certificates anyway.
   * Update Vcs-{Browser,Git} to point to salsa (alioth's replacement).
   * Set Acquire::Languages to none since translations aren't needed.
   * Avoid warnings regarding missing /etc/apt/{apt.conf.d,preferences.d}
     by setting their respective apt config variables to /dev/null.
   * Duplicate Apt::Architecture into Apt::Architectures because of course
     apt has two options, the latter getting foreign architectures if not
     specified, even if the former is.
   * Run fc-cache when /etc/fonts or /usr/share/fonts exist, to avoid
     having to generate UUIDs at runtime, which can be hard because of
     missing entropy (Closes: #898468).
   * Add fontconfig to Build-Depends accordingly.
 .
   [ Paul Tagliamonte ]
   * Add support for the NanoPiNeo
 .
   [ Aurelien Jarno ]
   * Drop the build-depends on libnewt0.52, the library now provides an udeb.
 .
   [ Vagrant Cascadian ]
   * [arm64] Generate u-boot media for pine64_plus:
     - Add Build-Depends on u-boot-sunxi, atf-allwinner, u-boot-tools and
       device-tree-compiler.
     - Add atf-allwinner to Built-Using.
   * [armhf] netboot: Enable grub-efi mini.iso.
 .
   [ John Paul Adrian Glaubitz ]
   * hppa: Use compressed kernel image by default.
   * sparc64: Use xz compression for initrd during netboot image build.
 .
   [ Paul Wise ]
   * Switch get-packages from setting apt-get options through the command
     line to writing a configuration file referred to by APT_CONFIG. The
     latter should ensure a stricter separation from the system config.
 .
   [ Samuel Thibault ]
   * Do not create /dev/console and /dev/null on hurd-any, they are initialized
     at runtime.
 .
   [ Vagrant Cascadian ]
   * [armhf] Add support for Cubietruck_plus.
