In my opinion Linux SW Raid is very stable. However, SW raid
stresses SCSI to its limit and any tiny error in the hardware
will show up very quickly. Also, not all drivers handle
the situation when a disk dies, they hang up the bus. As far
as I know the NCR/Symbios- and AIC7xxx-driver will not
hang up the bus. ECC-Ram is also a must.

Those are two completely different things.
