For a year, I workaround it by disabling NCQ & reducing the speed by booting with "libata.force=0:3.0Gbps,0:noncq". It turns out disabling LPM fixes it without the huge performance hit. Related: bko#222187 v2: - remove firmware revision - drop speed to 1.5Gbs - disable NCQ altogether (else we still see the errors from times to times) Example of errors last year: [999662.257282] ata3.00: exception Emask 0x0 SAct 0x2000 SErr 0x0 action 0x6 frozen [999662.257298] ata3.00: failed command: READ FPDMA QUEUED [999662.257302] ata3.00: cmd 60/20:68:40:7c:fb/00:00:d0:01:00/40 tag 13 ncq dma 16384 in res 40/00:ff:00:f6:00/00:00:00:00:00/00 Emask 0x4 (timeout) [999662.257317] ata3.00: status: { DRDY } [999662.257325] ata3: hard resetting link Example of errors this year: kernel: sd 0:0:0:0: [sda] tag#2 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#2 CDB: Write(10) 2a 00 64 10 48 70 00 20 00 00 kernel: I/O error, dev sda, sector 1678788720 op 0x1:(WRITE) flags 0x0 phys_seg 87 prio class 2 kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209848590) kernel: sd 0:0:0:0: [sda] tag#3 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#3 CDB: Write(10) 2a 00 64 10 2e 28 00 03 08 00 kernel: I/O error, dev sda, sector 1678781992 op 0x1:(WRITE) flags 0x0 phys_seg 88 prio class 2 kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209847749) kernel: sd 0:0:0:0: [sda] tag#4 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#4 CDB: Write(10) 2a 00 64 10 31 30 00 05 90 00 kernel: I/O error, dev sda, sector 1678782768 op 0x1:(WRITE) flags 0x4000 phys_seg 168 prio class 2 kernel: sd 0:0:0:0: [sda] tag#5 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#5 CDB: Write(10) 2a 00 64 10 36 c0 00 02 f0 00 kernel: I/O error, dev sda, sector 1678784192 op 0x1:(WRITE) flags 0x0 phys_seg 88 prio class 2 kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209848024) kernel: sd 0:0:0:0: [sda] tag#6 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#6 CDB: Write(10) 2a 00 64 10 39 b0 00 05 70 00 kernel: I/O error, dev sda, sector 1678784944 op 0x1:(WRITE) flags 0x4000 phys_seg 168 prio class 2 kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209848292) kernel: sd 0:0:0:0: [sda] tag#7 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#7 CDB: Write(10) 2a 00 64 10 88 70 00 20 00 00 kernel: I/O error, dev sda, sector 1678805104 op 0x1:(WRITE) flags 0x0 phys_seg 65 prio class 2 kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209850638) kernel: sd 0:0:0:0: [sda] tag#8 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=44s kernel: sd 0:0:0:0: [sda] tag#8 CDB: Write(10) 2a 00 64 10 a8 70 00 0e c0 00 kernel: I/O error, dev sda, sector 1678813296 op 0x1:(WRITE) flags 0x4000 phys_seg 168 prio class 2 kernel: sd 0:0:0:0: [sda] tag#9 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=39s kernel: sd 0:0:0:0: [sda] tag#9 CDB: Write(10) 2a 00 64 10 b7 30 00 11 40 00 kernel: I/O error, dev sda, sector 1678817072 op 0x1:(WRITE) flags 0x4000 phys_seg 87 prio class 2 kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209852134) kernel: EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 36831430 starting block 209852672) kernel: EXT4-fs (sda1): failed to convert unwritten extents to written extents -- potential data loss!
