Really?
Yes. You can't run Linux (or NetBSD, I hear) on LC040 macs because of
that bug.
Well you can, but it just crashes a lot. (Note that IIRC the early
revs of the non-LC 040 also suffered from the same bug, but since the
non-LC doesn't generate as many F-Line traps, only A-Line traps, it's
triggered much less frequently)
I'm still pretty sure that the bug can be worked around in the kernel
with some ugly exception checking, but I never got around to writing
any code to do it. Too many other bugs to fix at the time.
