This is a hardware bug, unfortunately. And it's also the reason why
discard is not on by default.
These days, what I normally tell people is to not use the discard
mount option at all, and instead use the fstrim program, run out of
cron maybe once a week or even every night if you are anal. (But for
most workloads, once a week is plenty.) The main place where the
discard option makes sense is if you are using a very expensive PCIe
attached flash device. Those devices are much more likely to have a
competently implemented DISCARD command, and they generally don't
destroy performance forcing a queue flush for every single DISCARD
request.
However, in your case, if discard commands are causing on-disk
corruption, I'm not sure I can even in good conscience recommend using
fstrim.

Instead, all I can do is suggest that you consider whether you should
replace your SSD. Historically, I've stuck with Intel SSD's because
they are the ones that have tended to be the most reliable. Intel has
unfortunately, been slow to market because they insist on testing
their products extensively and only releasing them when they are
solid, which has cost them market share. Unfortuantely, the market
doesn't always reward quality. More recently, I've started using
Samsung SSD's. I have a Samsung 840 PRO and the Intel 525 240GB mSATA
SSD's in my laptop, and so far, I've not had any problems with either.
They are definitely not the cheapest nor the most performant devices
in head-to-head testing, but that's not the only dimension that I care
about....
More (somewhat depressing) investigations about the quality of SSD's
these days:

- Ted
P.S. Some really crappy SSD devices have brick'ed themselves when
they are given a heavy discard load, particularly one which is mixed
with other traffic, and this is what the "discard" mount option
provides. Note that if the fstrim command is executed while you are
also trying to put the device under heavy read/write workloads, it
could also result in the same kind of corruption and/or brick'ing of
the SSD. Which is why I hesitate to recommend switching to fstrim for
a device which is known to mishandle the DISCARD command, and to
suggest simply not using the DISCARD feature at all --- and if this
results in increased performance lost or increased write wear, to just
replace the SSD as an inferior quality product before it does any
further damage to your data.

If this is not a production system you can try to switch to another
provisioning mode. I.e. Intel510 drives cause data corruption with
write-same-10, but unmap works fine.
cat /sys/class/scsi_disk/H\:C\:I\:L/provisioning_mode
and
echo -n {writesame_16,unmap} > /sys/class/scsi_disk/H\:C\:I\:L/provisioning_mode
(lsscsi can provide the H:C:I:L tuplet)
