Hi,
I came via
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/285892?comments=all
which said, it would be a duplicate of this bug. I experience the bug
after having changed from a legacy hdd to a ssd (ocz agility 3), running
Ubuntu 11.10, all cables are fine, but everytime there are excessive
write or read actions on this drive I experience a system freeze with
the following appearing in the syslog. This is perfectly reproducable by
just copying a big file.

The support from ocz told me, that I might have a chance resolving this by
either applying a firmware update or the "SATA3 to SATA2" fix. The latter
seemed very interesting to me, could it be the main reason for the whole issue?
I haven't tried yet since the ssd sits in an all in one pc that can't boot from
usb, has a broken dvd drive, and is not really built for being repaired often,
so I'd like to make sure it really solves the issue. And since I'm reading a
lot about people having no problems with another OS I keep on waiting for a bit
more ;)
Anyone got a opinion about this sata3 to sata2 fix or whether it's OS or
hardware connected?
