Has any bug been reported using a RAID 5 configuration with Hypercache? I have a 12-drive RAID 5 (TOS 6.0.694), and if I enable Hypercache (Balanced mode) the first few times the NAS boots, it boots fine. However, on the fifth or seventh boot, the disks become very active for a couple of hours after booting.
The md0_raid5 process also has a very high activity level. If I disable Hypercache, this doesn't happen.

I've tried disabling and re-enabling Hypercache several times, but the result is always the same.
