Ok, I was wondering if it was a known bug or something... hmm... I also
seems to get the bug on the debian patched 2.6.8-4 sources (had to
recompile with "Use one physical chunk of memory only" to get it to
work tough...)

Got some more info:
I've added some printk's in the kbd_keycode function...
When booting, it seems that the kbd_keycode() function is returning fine.
With booting, I mean, I can type on the keyboard from the point of
initrc, my printk's shows that it gets values from the kbd, and the function
returns, but as soon as I get to the point when booting is finished, as in
singleuser boot when it waits for the root passwd,
_then_ oopses are coming up when typing, and the system hangs, though it
continues to responce with oopses on each keypress and release.
I have printk's before and after abovementioned line
> > keysym = key_map[keycode];
when oopses are occuring: I only see the printk _before_ this line,
I'll attach dmesg output at the end of this mail.
I have no problems with 2.4.27. So it was kinda strange. It seems that
"everything else" works (I can safely work through ssh, as long as I dont
touch the kbd on the amiga, but havent tested it very hard...)
(the same oopses are on 2.6.8, but I havent tested that extensively)

Sorry about that! note that it occurs on debian -sources 2.6.8, and
I moved onto latest cvs to just check if it was happening there also.
I really dont know where to start debugging this, but since there seems to
several others that have working 2.6.x -kernels, this may be something
special (faulty?) about my system, my mainboard is stamped with "A4000cc
Rev D", and I have been told that it was one of the latest revisions
before the A4000 (and commodore) folded, and not so very common in the
market... but that is probably totally irrelevant. I'll continue debugging
and see if I can find out more... but as I'm no kernel expert, I'm just
fumbling in the dark here... hoping if anybody has some advice...
Okay: dmesg output:
Theese lines are my own:
--
keyboard.c: keycode=30, shift_final=0 ;
keyboard.c: done
--
just before, and just after the now famous:
keysym = key_map[keycode];
I'm typing 'b' (hex=30) on the keyboard several times, first, while in
initrc, when oopses occurs, the prompt waits on root password for
singleuser, sorry for not having the complete console output, only kernel
messages..

Hope all this stuff makes sense.
Perhaps someone can provide me a kernel-image that works for them, and see
how it works on my system? (with one phys. mem chunk option)?
Kind regards, Haakon
