What release of IPS-driver do You use? 1.0? (this is fine).
We are running LVM 0.7 on a NetFinitiy 5000-20 with ServeRAID 
for about 6 weeks without any problems.

Mh, hopefully You set up real partitions before using pvcreate!?
That means: the PV should be on /dev/sdb1, not on /dev/sdb!
If not, you do have a real problem :-(#)

The LVM-kernel driver says:

/*
 * this one never should be called...
 */
static void lvm_dummy_device_request(void)
{
        printk(KERN_EMERG
               "%s -- oops, got lvm request?\n", lvm_name);
        return;
}


Well, I did not check, but I think, switches and parameters
should be separated by space, i.e.:
	lvcreate -L 5000 -n reallv realvg

Hope, these hints are helpful
