New Revision: 228243
URL: http://svn.freebsd.org/changeset/base/228243
Log:
Add quirk for Micron RealSSD eUSB failing on unsupported SCSI command
It appears this device fails if sent a SYNCHRONIZE_CACHE command, so add
quirk to avoid sending it.
I will follow up with Micron on this issue, and will adjust the quirk if
necessary based on their feedback.
