https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222802 Bug ID: 222802 Summary: [patch] QUIRK: KingDian S200 SSD which crashes when receiving a TRIM command Product: Base System Version: 10.3-STABLE Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: bsdpr@phoe.frmug.org Keywords: patch Created attachment 186926 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D186926&action= =3Dedit KingDian S200 quirk preventing the kernel from issuing TRIM commands Inexpensive KingDian SATA SSDs are experiencing failures when issued a TRIM command. This can be observed when adding such a device as part of a zpool. Kernel reports a timeout on the TRIM command; then a timeout on the INQUIRY command; them the device reapears. It looks the SSD is crashing. The comman= d is retried, the SSD crash again, etc. The device identifies itself as ada1: <KingDian S200 60GB P0921B> ACS-2 ATA SATA 3.x device ada1: Serial Number <elided> ada1: 300.000MB/s transfers (SATA 2.x, UDMA5, PIO 512bytes) ada1: 57241MB (117231408 512 byte sectors) I was unable to keep track of the error messages as the system is unrespons= ive while he tries to handle this situation which ultimately require powering t= he host off to recover control. To resolve this I had to add a new kind of quirk to ata_da.c, I called it NO_TRIM. It simply clears the device's CAN_TRIM flag. When the quirk is in effect for that device it can then succesfully be used as part of a zpool. The quirk is applied to devices matching the "KingDian S200 *" pattern, the= re is currently two models in that line only differing in capacity: 60 and 120= GB.
