i can confirm that there seems to be a problem with 3ware controllers on 6-STABLE,
including a recent one (january 12th).
i started getting lockups on a server that was running smoothly on 4-STABLE,
but now it locks up regularly, about once a day.
the array is not rebuilding, and i don't get any messages in the logs.
my controller is also a different model, namely 8506 (twe driver).

so far i don't see any correlation with controller activity.
i had lockups on a fairly loaded (~50% disk load) controller,
and on almost idle (1-5%).

nothing is printed to the console and system is unresponsive, except for pings.
strange thing is, usually when there is a disk problem,
some activity is still possible - e.g., if you have a running shell,
you can still at least type or even use commands/work with files in cache.
not in this situation, though.

i will try to investigate further, maybe try downgrading to 5.x
