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... -- Sebastian Kuzminsky - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
