I realize this is a worthless bug-report, but where does that message come from? The text is nowhere in the kernel-sources, so it must be something else. Greetings, Jurriaan -- HORROR FILM WISDOM: 1.

Without gdb, it always prints Trace/breakpoint trap and no other output. The C200 then hangs, 90% of the time even the power-switch doesn't work. I'm getting some sort of yoga-training just trying to reach behind it for the power-cord :-) Since I don't know how to get earlier kernels (it doesn't work in 2.4.9-pa13, it works with 2.4.0 from the 0.9.2 iso) I can't do anything else than whine about it again. Sorry about that. Jurriaan -- HORROR FILM WISDOM: 3. Do not search the basement, especially when the power has just gone out.

Since this seems to happen with 2.4.9-pa13 and not with 2.4.0 from the 0.9.2 ISO, perhaps I ought to do some checking when exactly it broke. Can anybody point me to a quick cvs reference, starting with cd [somewhere] tar zxvf linux-latest.tar.gz and then? I'm only interested in extracting certain kernel-versions (by date?).
