I just tried this and it hung again, with nothing in the logs or on the console.
Pretty wierd.
I just had another hard lockup with sata_mv -> Raid-6, but without LVM. This is new for me, first time I've seen it lock up without LVM. I was resyncing the raid array and running 'badblocks -svn' on it (/dev/md1) at the same time, and it locked.
I'm going to shelve the Marvell 6081 controller for a while, and go buy something else...
