R710 H700 FreeBSD 8 crashes

[no wonder]

Is anyone using Freebsd 8 successfully on R710s w/ PERC H700 in a raid 5 ?

We've got 6 1TB sata's configured in a raid 5 on the H700.

I've been getting page faults and kernel panics recently and would like some
pointers to figuring out what's happening .

I've fsck'd -y partitions upon reboot as required to bring the system back.

Freebsd is using the mfi driver.
