It's not installed in our C3600 at the moment,
but it seems what we observed 2 days ago with Highpoint RocketRAID
1640HTP374 card
it's PCI 32bit, 4 SATA channels, it doesn't crash, but it randomly
offers file corruptions.
The dmseg shows a lot of DMA errors.
How to investigate? I am not a kernel developer, but rather an HDL-guy (FPGA)
