    Reproduced successfuly on 386 with hercules, could not reproduce on
    pentium with vga.

    Could it be some math-emulation problem? I doubt it.

    Here is trace, it was done by hand (so I spent lot of time doing it
    and there may be bugs)...

    ...

    What I see is keyboard interrupt coming into the middle of
    console_bh(), causing havoc. OOk, I'll investigate some more.
