Public bug reported: [Impact] Several issues have been fixed upstream in the hisi_sas driver: - Driver may configure the wrong signal attenuation setting - Driver may not negotiate the correct max link rate supported by the phy - phy must be disabled before trying to change its link rate - Internal abort timeout doesn't take into account link negotiation time - Driver returns incorrect values to upper levels
[Test Case] Regression testing on D05 and D06 systems, which have different versions of this controller. [Regression Risk] Code changes are restricted to the hisi_sas driver, and the HisSilicon D05 and D06 are the only two boards Ubuntu supports that use this driver. Explicit testing on these two boards should mitigate the regression risk. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: dann frazier (dannf) Status: In Progress ** Affects: linux (Ubuntu Bionic) Importance: Undecided Assignee: dann frazier (dannf) Status: In Progress ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Bionic) Status: New => In Progress ** Changed in: linux (Ubuntu Bionic) Assignee: (unassigned) => dann frazier (dannf) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768974 Title: Several hisi_sas bug fixes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768974/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
