charset=UTF-8 Content-Transfer-Encoding: 8bit Without that, I get the errors below. For a year, I workaround it by disabling NCQ & reducing the speed by booting with "libata.force=1:3.0Gbps,1:noncq". It tried out disabling LPM only but I was still able to see errors. Related: bko#222187 v3: - add firmware revision check v2: - remove firmware revision from SSD name - drop speed to 1.5Gbs (as there's no 3.0Gbps quirk) - disable NCQ altogether (else we still see the errors from times to times) Example of errors: ata1.00: exception Emask 0x0 SAct 0x1c SErr 0x0 action 0x6 frozen ata1.00: failed command: WRITE FPDMA QUEUED ata1.00: cmd 61/00:10:00:a8:a9/20:00:6f:00:00/40 tag 2 ncq dma 4194304 ou res 40/00:ff:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1.00: failed command: WRITE FPDMA QUEUED ata1.00: cmd 61/40:18:30:ce:51/05:00:39:00:00/40 tag 3 ncq dma 688128 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1.00: failed command: WRITE FPDMA QUEUED ata1.00: cmd 61/50:20:70:d3:51/02:00:39:00:00/40 tag 4 ncq dma 303104 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1: hard resetting link ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310) ata1.00: configured for UDMA/133 ata1: EH complete sd 0:0:0:0: [sda] tag#10 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=43s sd 0:0:0:0: [sda] tag#10 CDB: Write(10) 2a 00 6e e6 88 00 00 10 00 00 I/O error, dev sda, sector 1860601856 op 0x1:(WRITE) flags 0x4000 phys_seg 32 prio class 2 EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 33841832 starting block 232575232) sd 0:0:0:0: [sda] tag#11 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=43s sd 0:0:0:0: [sda] tag#11 CDB: Write(10) 2a 00 6e e6 98 00 00 20 00 00 I/O error, dev sda, sector 1860605952 op 0x1:(WRITE) flags 0x4000 phys_seg 64 prio class 2 (…) EXT4-fs warning (device sda1): ext4_end_bio:360: I/O error 10 writing to inode 33841806 starting block 232583424) EXT4-fs (sda1): failed to convert unwritten extents to written extents -- potential data loss!
