It does not seem CPU specific, breaks for both 486 and Pentium with the same
error.

And this is where everything seems to go wrong: When I compile buffer.c with
2.95.2, and link everything together, the kernel magically boots without any
complaints; later on something starts crashing badly, but this might be other
issues that can be investigated later on.
> But now I have almost no clue what really goes wrong
... and now I have a bit more, and the suspection that something broke the
way in which the kernel_thread function (arch/i386/kernel/process.c) wants to
start the kernel threads, here bdflush and kupdate. I don't understand all
issues completely, but something seems to have changed.
Attached are the relevant (?) portions of the assembly output for buffer.c:
kupdate, bdflush and bdflush_init, compiled with 2.95.2 and 2.97,
respectively. Perhaps someone could look over it?
Thanks and happy hacking,
Andreas
