I felt I could not name a single author (“From”) which
is why I submitted this as-is.

>Tested-By: Thorsten Glaser <tg@debian.org>

I’m successfully running this on my buildd VM now, with the
patch to use generic div64.h instead of machdep one; dmesg
follows. I’m also building a kernel package with Andreas’
patch, expected to be compiled at about 16:00 UTC tomorrow
if past times are reliable, and will send a Tested-By line
for that patch too afterwards.

Debian 3.10.5-1+m68k.1 is
• generic div64
• this interrupt patch

Debian 3.10.5-1+m68k.2 will be
• machdep div64 with <871u633t27.fsf@igel.home> applied
• this interrupt patch

Sometimes they [people] care too much: pretty printers [and syntax highligh-

detail in the program, which is as sensible as putting all the prepositions
in English text in bold font.	-- Rob Pike in "Notes on Programming in C"

It really was Geert's work, I did not meaningfully contribute to that.

Having revived my Falcon, I should be in a position to test these.

Hm okay. Let’s just hope Geert hurries up and accepts them into

OK cool. The latter is only available now, having replaced the

BTW, the interrupt patch only kills some messages at boot, right?
Or does (the lack of) it cause real errors later?

I’m not entirely sure, but the “scary-looking” boot messages

Might not make much of a difference in ARAnyM - that's why I want to  
test it on the real hardware. The way things are going, not before

Support for it was in squeeze, and first packages begun to
use it shortly afterwards, so for years. I think I even saw
it being used before squeeze, for leaf packages such as -dbg
ones or those with huge data.

On the other hand, to actually *boot* a system successfully
with this kernel you need an initrd, which requires a system
up to date as of roughly end of 2012, anyway (due to the
initramfs-tools package and the versions of the packages
that are actually needed to be put *on* the initrd, and due
to the initrd being expected to be xz IIRC). So I'm afraid
you need to boot into at least Linux 3.2 first - images are
at http://snapshot.debian.org/package/linux/3.2.35-2/ and
also require xz to unpack already, but that can be done on
any Unix box (even BSD) using ar and tar; those are mostly
monolithic and don't require an initrd to boot - then to
dist-upgrade your system to latest unstable, at which point
you can apt-get install the 3.10 kernel.

I must admit I'm using Ubuntu LTS releases mostly, so 'years' might be 
the right ballpark.

I assumed the initrd was pre-built and included in the package. Silly 
of me.

Much easier to integrate the patch in question into my 3.10 git tree.

Thanks,

Haha…

No, that’s not how they work (which is the reason for much annoyance
and reluctance on my part to switch to using initrd, and the reason
for me asking around on how to port kexec to m68k).

FWIW, that patch was in Debian linux-image-3.10-2-m68k
so everyone who successfully booted that counts.

Scott Holder booted it on his Macintosh AFAIR.

In Debian unstable: apt-get install linux-image-3.10-2-m68k
(or better linux-image-m68k which is the metapackage).

The .deb is not usable outside of a running unstable installation.

If you “just” want to test the kernel:
http://www.freewrt.org/~tg/f/vmlinux-3.10-2-m68k.gz

Maybe this initrd (generated on the Atari VM buildd) can
work for you somewhat (but this is totally unsupported,
and you really must install the kernel in an up-to-date
Debian unstable system for reliable operation):
http://zigo.mirbsd.org:8080/t/initrd.img-3.10-2-m68k

Do you get segfaults on aranym when you create the initrd? I get lots on
crest and kullervo, I am not sure iif it is always in the same place.
Probably some modules are not working then, so maybe one initrd for all
would be a good option. I do have the impression that with 3.10 there are
less segfaults than before, but I can not quantify that...

No and I never get them at all during normal system operation, only
for testsuites of some packages that either are buggy or use buggy
code.

Such a thing does not exist for Debian.

They’re on debian-ports, not debian.org, of course.

There are some use*ful* new dependencies: stuff to generate the
initramfs, which is now REQUIRED for the Debian distro kernel.

>I'm using a 3.10-rc2 from GIT in a etch-m68k distro and it works fine.

A self-compiled monolithic kernel will run fine, sure, but we
switched to requiring an initrd for 3.10 in Debian.

This *will* not work with etch-m68k.

Also, the *.deb files are now xz compressed instead of gzip,
which needs squeeze or newer.

Thanks, but what is the URL, I want to wget it. I didn't find it on
ftp.debian.org.

Why ? There are some (useless) new dependencies ?

I'm using a 3.10-rc2 from GIT in a etch-m68k distro and it works fine.
