SubjectThis can freeze linux 2.0 on 486
Date
Hi all,

Recently I saw this behaviour on linux 2.0 running on i486.

Instruction invd ( supposed to invalidate cache) can lock the m/c
completely.

Put Instruction invd in assembly file, assemble and link and
see the consequences. I am not sure whether this is a 486 bug or
linux bug.

BTW invd is a privileged instruction on Pentium I am not sure
about 486.
