I've got a pair of FA312 cards and this problem has bothered me
for ages. This has finally prompted me to do something about it :)
Turns out that somebody wasn't following the documentation. We were
doing 16-bit writes to 32-bit registers which led to some addresses
working and others not so lucky.
This patch should fix the problem.
