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.
