Well, the problem is that it doesn't happen very often (only two
systems it happened to once), i.e. not reproducable, and to make matters
worse, we have 100+ systems in the field at client sites, so, w/o a
definate YES this fixes it, we can't really go around upgrading
firmware..

Plus, we have a lot of older cards, where the current firmware is
2.34 (though we are running on 2.32 for many of our cards)...  so, we
can't use the really new firmware...
