This is perhaps a bug, or broken issue, too. We're having problems running
this snapshot on i486's. We use the same tree as we do for Pentiums (and
higher), but with different CPU configs of course. The kernel first seems
to boot correctly but then dumps the context and prints a:
/* Hand written dump begins here ... */

We use a separate PC (PII 350MHz) to compile the kernel (gcc 2.95.2).
An unpatched version of Linux 2.3.99-pre3 compiles and boots just fine
on the i486's, but the patched version doesn't (no rejects from the
patch).
It's very strange, especially since we use the same setup (except for
the CPU options etc.) for a Pentium 90 where RTLinux boots just fine.
Any suggestions?
