I have a patch against stable/8, but not stable/9:

Running with that in an otherwise 8-STABLE GENERIC amd64 kernel, I'm getting:
kstat.zfs.misc.zio_trim.zio_trim_bytes: 0
kstat.zfs.misc.zio_trim.zio_trim_success: 0
kstat.zfs.misc.zio_trim.zio_trim_unsupported: 0
kstat.zfs.misc.zio_trim.zio_trim_failed: 2742
which doesn't look like it's working. The SSDs are:
ad4: 114473MB <ADATA SSD S510 120GB 3.3.2> at ata2-master UDMA100 SATA 3Gb/s
ad6: 114473MB <ADATA SSD S510 120GB 3.3.2> at ata3-master UDMA100 SATA 3Gb/s
Any suggestions? Thanks
Don't think ad supports TRIM, switch to ada (ahci) and you should be good.
Although I'm surprised your seeing that many reported failures as it should
have disabled it on a pool level after the first few failures.
Is it still increasing?
