https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222802 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=186926&action=edit 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 command 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 unresponsive while he tries to handle this situation which ultimately require powering the 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, there is currently two models in that line only differing in capacity: 60 and 120 GB.
