N5200BR frequent freeze up

[praetorchu]

I would appreciate any help on this matter. NAS is unusable in its current state.

N5200BR with firmware 2.00.10
5x Samsung HD501LJ (disk health OK)
Raid 5

NAS would freeze up during file copy. This is reproduceable with 1) file manager copy to SMB 2) rsync copy. Copy operation would start and NAS would freeze up after < 1GB of data copied.

NAS responds to ping
NAS does not respond to SSH
NAS does not respond to SMB browsing from file manager
NAS does not respond to web interface access
NAS does not respond to reset button on front of unit

Only way to recover is to hold down power button and do a power down then power up again.

I have tried the following:
Re-flash firmware to 2.00.10
Delete and re-create raid5
Run file system check
