My Samsung 860 EVO mSATA 500GB SSD lockups for 20-30 seconds on fstrim, while dmesg is repeatedly flooded with:
[ 332.792044] ata14.00: exception Emask 0x0 SAct 0x3fffe SErr 0x0 action 0x6 frozen [ 332.798271] ata14.00: failed command: SEND FPDMA QUEUED [ 332.804499] ata14.00: cmd 64/01:08:00:00:00/00:00:00:00:00/a0 tag 1 ncq dma 512 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) [ 332.817145] ata14.00: status: { DRDY }
Disabling queued TRIM for it, as already done for the 850 series models, solves the issue completely.
