The 2940 cards are old. Could it be that your PCI bus it too fast or
something. If that is the case, you may either have to 'under-clock' the
PCI bus OR just toss these cards and get Adaptec's newer cards.

There is a well known thing where these cheap pata fakeraid cards will try to do ata133 if the drive says it can, when really, even if he drives are new ata133 drives and the cables are new and short and shielded, you still shouldn't try to do ata133 since the spec is too tight and you'll just get bit errors or other failures. ... The fix is use ata100 somehow, either by disabling dma entirely in loader.conf (since you have no more selective option there, and the raid card bios never has an option for controlling pio/dma mode like motherboard bios's have) and then use atacontrol in rc.early to set udma5, or by using disks that can only do ata100 and only advertise ata100 to the controller. ...
