File a new bug at bugzilla.kernel.org describing this problem. Include make/model of all involved SSDs, which you can get from smartctl or hdparm. And then do a strace fstrim on the working and non-working volumes, saving the output to separate files and attaching them to the bug report. And then it's probably best to create a new list thread to post the URL for the bug, since this thread is really about two problems that may not be related.
