This system is standard PC loaded with a bunch of SATA disks (15).
8 on a LSI raid card
the remaining on standard SATA port on the motherboard.
This is primarily a NAS for the LAN (Samba&  netatalk).

We're getting random crash of the system (panics, GPF). Stack trace is always 
different.
Can you check that the power supply is sufficient for all these disks?
Do you have recommendations ? I haven't found so much information on how to estimate the power need. Currently this is a 600W power supply (FWIW: Cooler Master Silent Pro M - 600W)

It would also be sensible to enable ECC on such an important machine.
This requires specific RAM chips, does it ?
