Hello,

This is my first Bugzilla report, so I appreciate your patience!

I recently purchased a Highpoint 840A RocketRAID Controller with eight
connected Samsung 860 EVO SSDs . Unfortunately, the "SCSI_HPTIOP" kernel
low-level SCSI driver module does not detect this controller. It appears that
the 840A is a smaller version of the 3740A, which is already supported by the
kernel. The main difference seems to be that the 840A supports only 6Gb/s per
channel, as indicated by the product markings on the card.

I am currently using the latest firmware version 1.0.0 for the controller. I
couldn't find any other driver modules that might be compatible with my
controller. The drivers available from Highpoint for Linux do not work on
(Gentoo) Linux. The controller and SSDs
(https://serverorbit.com/solid-state-drives-ssd/sata-6gbps-ssd) are functioning
perfectly under Windows 10, so the hardware is not faulty. I am using a
Gigabyte X99-SLI motherboard with BIOS version F24a.

I am willing to provide regular dump logs for driver debugging if needed. I
would be extremely grateful if support for this hardware could be included in
the next kernel release!

Here is a top-down view of the expansion card for reference:
