The Lenny kernel sets CONFIG_KEYBOARD_HIL_OLD=m, does this still apply?

Moritz, thanks for bringing this up again. I nearly forgot it!

I just tried the netboot image dated 30-10-08 from
http://ftp.nl.debian.org/debian/dists/testing/main/installer-hppa/current/images/netboot/2.6/.

Currently the debian installer boots up nicely, but the keyboard is not
functional at all (on machines with HIL keyboard).
My tests with booting via serial console shows, that all what needs to
be done to get those keyboards working now is, to run a
"modprobe hilkbd"
at startup.

Is it possible that someone from the debian-installer teams add this
"modprobe hilkbd" somewhere to the bootup process? This modprobe should
also be carried over to the installed system afterwards.

I'm willing to test any temporary images (preferably netboot images) as
soon as possible.

Helge

[Forwarding to debian-boot@lists.debian.org]

Can that be considered for rc2?

Cheers,
Moritz

Yes, please.
I should have mentioned, that adding "modprobe hilkbd" will not break
any parisc machine which does not have HIL. So it's pretty safe to probe
for this module.

Why not (also) reassign the BR to debian-installer?

> Can that be considered for rc2?

Theoretically that would still be possible, but it is extremely late in
the day for such a change, especially without any detailed info about how
*exactly* this should be implemented.

Questions that come to mind are:
- why doesn't the kernel/udev autoload this module?
- is there any way to recognize whether the module should be loaded or
not (most hppa installs are headless)?
- if it's decided to load the module unconditionally for the installer,
it may still be possible to only do so when needed for the installed
system; can this be recognized somehow?
- is loading the module for the installed system needed for the initrd
too (would be my guess), or just for the final system?

We have repeatedly indicated in the debian-hppa list that the D-I team
needs porter support and this is *exactly* the kind of issue for which
knowledgable porter support is needed. I even had a long discussion with
Helge himself about that.

As this issue has been known for ages my first reaction is that it is too
late for RC2 and for Lenny. However, *if* porters work with the D-I team
to get the questions above answered the change could be implemented early
for squeeze and, after testing, it could then be considered for
backporting for a stable update release.

Cheers,
FJP

It didn't know about that specific source package, reassigning now.
