Hi. I noticed that my Crucial M550 SSD (firmware MU02) is missingly recognized as quirk ADA_Q_NCQ_TRIM_BROKEN. If I understand the source (introduced first at r298002, before stable/11 branched) correctly, only firmware MU01 should be recognized so for the SSD model, so I have no idea why. :-( Below are the related portion of dmesg. stable/11 at r304189, amd64. (Built with options CAM_IOSCHED_DYNAMIC.) ada0 at ahcich0 bus 0 scbus0 target 0 lun 0 ada0: <Crucial CT1024M550SSD1 MU02> ACS-2 ATA SATA 3.x device ada0: Serial Number ************ ada0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 976762MB (2000409264 512 byte sectors) ada0: quirks=0x2<NCQ_TRIM_BROKEN> Steering write from 0 kBps to 300000 kBps One thing to note: The SSD was shipped with MU01 and updated to MU02 using CD image obtained from Crucial Japan website. Need Bugzilla ticket although it's not a severe problem (goes safer side, and easy to workaround via loader.conf)? -- Tomoaki AOKI <junchoon_at_dec.sakura.ne.jp>Received on Tue Aug 16 2016 - 12:01:22 UTC
