Public bug reported: [Impact] Early ThunderX silicon may hang when initializing the SATA controller.
[Test Case] This was found in a reboot loop. The latest ThunderX2 firmware (3.1) enables hardware error interrupts and when the reset fix fails, we get a hang with the print: [ 14.839308] sd 1:0:0:0: [sdb] 468862128 512-byte logical blocks: (240 GB/224 GiB) [ 14.846796] sd 1:0:0:0: [sdb] 4096-byte physical blocks [ 14.852036] sd 1:0:0:0: [sdb] Write Protect is off [ 14.856843] sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 14.866022] ata2.00: Enabling discard_zeroes_data *** NBU BAR Error 0x1e25c *** AddrLo 0x1d80180 AddrHi 0x0 [Regression Risk] The fix is only compiled in on arm64, and only activated at runtime on this specific revision of silicon, so regression risk will be limited to a single platform that is only being distributed for development purposes. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: dann frazier (dannf) Status: In Progress -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1724117 Title: thunderx2 ahci errata workaround needs additional delays Status in linux package in Ubuntu: In Progress Bug description: [Impact] Early ThunderX silicon may hang when initializing the SATA controller.
