The following is the .config option that needs to be set for reliable
operation with the DPT cards:
CONFIG_SCSI_EATA=y
We have not found the driver configured with the following define to be stable:
CONFIG_SCSI_EATA_DMA
The instability is especially profound in an SMP environment. Under
any kind of load there will be crashes and hangs.
We have a fair amount of experience with DTP-3334UW cards in IMAP
based messaging servers. We had a lot of problems until we discovered
the difference between the two drivers.
With the proper driver the DPT cards have been as reliable as a
bowling ball. Not very fast but extremely tough and reliable.
