I am building a new system using an Kingston 240GB SSD drive I pulled from my
notebook (when I had to upgrade to a 500GB SSD drive). Centos install went
fine and ran for a couple days then got errors on the console. Here is an
example:

Eventually, I could not do anything on the system. Not even a 'reboot'. I had
to do a cold power cycle to bring things back.

Is there anything to do about this or trash the drive and start anew?

Make sure the cables and power supply are ok. Try the drive in another machine
that has a different controller to see if there is an incompatibility between
the drive and the controller.

You could make a btrfs file system on the whole device: that should say that
a trim operation is performed for the whole device. Maybe that helps.

If the errors persist, replace the drive. I´d use Intel SSDs because they
seam to have the least problems with broken firmwares. Do not use SSDs with
hardware RAID controllers unless the SSDs were designed for this application.
