Bug ID: 198975
Summary: Highpoint 840A RocketRAID Controller and drives are
NOT detected by SCSI_HPTIOP kernel module
Product: SCSI Drivers
Version: 2.5
Kernel Version: 4.15.7
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Other
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Hello,
This is my first kernel bugzilla report, so please have mercy ;-)
My freshly bought Highpoint 840A RocketRAID Controller and its 8 connected
"Samsung 860 EVO" ssd harddrives are NOT detected by the "SCSI_HPTIOP" kernel
low-level scsi driver module, but it seems to be the smaller brother of the
already from kernel supported 3740A RocketRAID controller by Highpoint.
The only differnence seems to be that the 840A supports only 6Gb/s per channel.
Thats is also confirmed by the top down view onto the expansion card.
In the upper right corner you can see the described dual product markings
"RocketRAID 3740A/840A", so the layout and most likely also the raid processor
of the controller has been used at least twice by Highpoint.
My controllers firmware is the recent 1.0.0 version.
I couldnt find any other driver module that is matching my controller more
closely.
The current published linux drivers by highpoint are useless under (Gentoo)
Linux.
The controller and its connected drives are working flawlessy under Windows 10,
so its not damaged. I am using a "Gigabyte X99-SLI" motherboard with recent
F24a bios version.
I am also willingly able to provide regular dump logs to kernel developers for
driver debugging.
I would be VERY thankful for including support into the next kernel for this
cool piece of hardware!

dmesg outputs only this, then nothing else related to my controller:
