https://bugzilla.kernel.org/show_bug.cgi?id=198975 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: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx Reporter: mae.lippert@xxxxxxxxx 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!
