Updated installation images for Debian Ports 2019-05-09

Hello!

I just uploaded updated installation images 2019-05-09 for the
following Debian Ports architectures:

 * alpha
 * hppa
 * ia64
 * m68k
 * powerpc
 * ppc64
 * sh4
 * sparc64

I uploaded both CD images [1] as well as netboot images [2].

Please test those images and report back over the mailing list for
the corresponding architecture.

Known issues:

 * alpha
   - There have been reports about missing firmware for storage devices.
     The firmware required for these devices is located in the
     "firmware-linux" and "firmware-linux-nonfree" packages but currently
     don't have a floppy driver in debian-installer to load additional
     firmware. I will figure out how to build CD images including firmware
     similar to the images available for i386 and amd64.
   - The images now includes the pata-modules package so users previously
     missing PATA drivers should be able to install their machines now.
 * hppa
   - No known issues and changes.
 * ia64
   - The kernel might be unstable during install
     (try passing "hardened_usercopy=off" at the boot prompt,
      e.g. "install hardened_usercopy=off").
   - If the machine locks up during boot with a radeon GPU,
     try passing "modprobe_blacklist=radeon nomodeset".
   - The installer has been switched to boot using GRUB now,
     ELILO is no longer available.
 * m68k
   - The drivers for IDE hardware may have to be loaded manually, e.g.:
     + modprobe pata_gayle
     + modprobe pata_falcon
   - There is no automatic installation of the bootloader yet,
     users have to boot the kernel and initrd manually after
     installation.
 * powerpc/ppc64
   - The bootloader installation still defaults to Yaboot and
     is being switched to GRUB for IBM POWER and PowerMacs,
     please report any issues you find.
   - Unfortunately, upgrading the GRUB package will currently
     render PowerMacs unbootable. See this thread for more:
     https://lists.debian.org/debian-powerpc/2019/04/msg00165.html
   - On some machines, the fans might produce a lot of noise,
     this can be addressed by manually the windfarm kernel
     modules:
     + modprobe windfarm_core
   - The installer has been switched to boot using GRUB now,
     Yaboot is still in the archives but will be removed
 * sh4
   - There is no CD image, installation has to be performed
     using the debian-installer images.
   - Currently supported targets are Renesas SH-7785LCR and
     SH-7751R, the latter should be identical to qemu-sh4.
   - debian-installer for sh4 is completely untested, please
     test with QEMU and report back. 
   - The filenames for kernel and initrd still contain an
      old 2.6.32.5 kernel version. This can be ignored.
 * sparc64
   - Installation over a serial console is currently broken
     on sparc64 due to a bug in the rootskel package
     (can also be considered a kernel bug), see: #926539.
     Use any image before 2019-04-06 as workaround.
   - The installer has been switched to boot using GRUB now,
     SILO is no longer available.

Important:

When reporting issues or bugs, please include the syslog
from your installation in the bug report/mail. The log
file can be access when switching to another console using
<Alt>+<Cursor> for normal installations or <Ctrl>+<a>+<n>
when installing over a serial console. I also need to know
what hardware was used, which installation steps (normal
vs. expert) and which image was used.

I am currently collecting bug reports but cannot push the fixes
immediately as the imminent Debian Buster release means that
debian-installer and components are effectively frozen.

Thanks,
Adrian
