However it should be noted that while the commit referenced is not in the mainline kernel anymore, a narrower blacklist applying to 840 and 850 models currently is [1]. And as the report is about the 850 Pro, queued TRIM should not have been the cause, as is already blacklisted in kernel for all "Samsung SSD 850". Can check in 'dmesg' for a note about it shortly after the SSD detection to confirm. [1] https://github.com/torvalds/linux/blob/master/drivers/ata/libata-core.c#L3952 -- With respect, Roman
