https://bugzilla.kernel.org/show_bug.cgi?id=202425 Bug ID: 202425 Summary: 3w-9xxx: 3ware 9650SE-2LP RAID controller not working on AMD Ryzen system Product: SCSI Drivers Version: 2.5 Kernel Version: >= 3.11 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other Assignee: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx Reporter: robert.smith51@xxxxxxxxxxxxxx Regression: No Created attachment 280811 --> https://bugzilla.kernel.org/attachment.cgi?id=280811&action=edit dmesg excerpt The 3ware 9650SE-2LP controller used to work fine on all kernel versions with my previous Intel Sandy Bridge (i7 2600k/P67) system. I replaced the mainboard and CPU with a Ryzen 7 2700x on an Asus ROG Strix X470-F mainboard while maintaining the same OS installation as before. Afterwards, the RAID controller was no longer properly initialised and is inaccessible as a block device. Instead, the driver produces error messages during the boot process (see below) This does not appear to be a hardware issue, because I was able to get the controller working with vanilla kernels of the 4.10 series (up to and including 4.10.17) as well as all of the versions of the 4.09-LTS kernel that I have tested. It does not work with any 4.11 kernels or later, up to and including 4.20.4. -- You are receiving this mail because: You are watching the assignee of the bug.
