Hmm, that should not happen. Normally the problems fixed by
this are expected to be very rare and you also should not get
sync flood, but just cache line corruption. While it might be possible
for random corruption to then cause sync flood that should be again
rather unlikely. If it's repeatable quickly something else
must be wrong.
Sorry, I missed the last sentence. This bug is reproduced by copying a
large file(8G) and in the meanwhile compiling a linux kernel for about
1 to 2 days.
