https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=191810 Bug ID: 191810 Summary: some SSDs should use UNMAP instead of ATA_TRIM Product: Base System Version: 10.0-RELEASE Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Many People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: michael@supermathie.net System: FreeBSD fearless2 10.0-RELEASE-p7 FreeBSD 10.0-RELEASE-p7 #0: Wed Jul 9 12:19:19 EDT 2014 root@fearless2:/usr/obj/usr/src/sys/CAMDEBUG amd64 On my SSDs (IBM TX21B10400GE8IBM) UNMAP should be used instead of ATA_TRIM as UNMAP seems much more reliable. Using TRIM, I get frequent timeouts: http://pastie.org/pastes/9368423/text?key=i4gmruxdtjars9fduq8w (da6:mps1:0:5:0): ATA COMMAND PASS THROUGH(16). CDB: 85 0d 06 00 01 00 03 00 00 00 00 00 00 40 06 00 (da6:mps1:0:5:0): CAM status: Command timeout (da6:mps1:0:5:0): Retrying command Is it possible to default to using UNMAP, if not for everything than for whitelisted devices? -- You are receiving this mail because: You are the assignee for the bug.
