Megaraid has *consistently* been a source of serious problems,
requiring firmware updates, performing very poorly with server class
operating systems that do not have last week's, not yet tested, beta
drivers, and corrupting data at unpredictable times. If ordering high
reliability equipment, I vastly prefer to go with Adaptec server class
hardware, which is somewhat mre expensive, or Rocketport, which has
been rock soled everyt time I'm privileged to use it.

I've also seen some ghods-awful 3rd party repackaged, no-name  cards
that are listed in the kernel as "Adaptec" and other vendors, but if
you look carefully had burned off chip numbers and look like they were
manufactured by monkeys. Poor trace quality, poor component mounting,
extremely thin gold on the contacts, gigantic screw holes to make
assembly easier but make the mounting plates drift in alignment, etc.

You might take a look at the actual card and make sure it's not one of
these "it fell off my uncle's truck" pieces of hardware.
