I just uploaded updated installation images 2019-04-20 for the

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.

I just tried the 2019-04-20 ISO on my DS25. Unfortunately the disc drive
cannot be detected by the installer so I'm stuck at this point.

Checking the drivers available in the shipped initramfs, there seems to
be only one PATA driver available - `pata_sis` - and according to [1]
this is actually a dependency of a SATA driver.


The missing driver for my machine is `pata_ali`, but as said the other
PATA drivers are also missing. From [2] and [3] I'd expect them to be
included, but this seems to be not the case for an unknown reason.



Loading this driver manually when using a NFS root FS makes the disc
drive accessible on my DS25:

UPDATE: On second thought, [2] and [3] seem to be unrelated to what is
available in the initramfs of the installer. From what I saw, the
drivers from the sata-modules UDEB are actually included in the
initramfs, but the needed drivers from the pata-modules UDEB are not.

Where is this configured? [4] includes the sata-modules UDEB as
optional, but no pata-modules UDEB. So is this maybe configured in [4]?
If yes, I can provide a patch on salsa.d.o to fix that issue, just need
a confirmation.
