Tom,
The 2.6.18 kernel (it is actually 2.6.18.5 plus some patches) we
currently have in Debian works fine on my SS20. You can find the
config, kernel, and matching initrd at
http://www.wooyd.org/sparc/
The only patch which touches anything in arch/sparc is also included
there (bus-id-size.patch), other patches may be viewed at
http://svn.debian.org/wsvn/kernel/dists/sid/linux-2.6/debian/patches/
One esp problem I'm aware of is broken CD-ROM support, the bug report
with some discussion is available at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=393894
I've got as far as figuring out that this problem seems to be due to a
miscompilation with gcc 4.1. If the kernel is built with gcc 4.0,
CD-ROM actually works again, so it might be some tool chain
regression. At this point, however, I don't really have time to track
it down.
For information, the 2.6.19.1 runs better when it is built with
gcc-4.1. I have tried to rebuild this kernel with gcc-4.0 and I can see
several deadlocks.
Regards,
JKB
