So try first just forcing DCACHE_WORD_ACCESS off (easily done by just
removing the "select" line in arch/x86/Kconfig).

If that fixes things, it really is the word access code.

But if the problem persists and it's a different bug, try to bisect it
with that DCACHE_WORD_ACCESS config option always forced off, just to
avoid any mixing of issues, exactly because we did have that one bug
that already got fixed that looked somewhat similar..

I'll test the current -git kernel on a F16 machine I have, just to
check. But I'm also assuming that there is something specific about
your setup, because otherwise I'd have expected many more reports
about this...
