As suggested by the above URL and also by
http://www.howtoeverything.net/linux/hardware/ubuntu-freeze-issue-after-ssd-upgrade
(which also mentions freeze issues with swap) I've set
libata.force=noncq, which made the error disappear. The error
no longer occurs after reboot without this kernel parameter.
Still wondering whether this is a general issue with SSD and
something can be done in the kernel.
