Success! By not mentioning "triggering keywords", the support person
wasn't offered the normal form-letter reply, and had to actually read
what I said. As a result, they replied with the direct email to their
firmware department and asked me to send the technical report to them.
I've now done so. Maybe we'll see a solution to this after all.

Bug description:
Hi,
after updating Samsung SSD 840 EVO to the latest firmware (EXT0DB6Q) the fstream command doesn't work anymore. Besides, there are a lot of file system errors and "bad sectors" reports. The problem is certainly caused by Samsung's firmware but I reported it as a bug because in Windows TRIM works normally after the upgrade. I have attached an image uploaded by a user who is experiencing the same problem. If you execute the command "sudo fstrim /" the console gets stuck. If you add that command in rc.local the boot is compromised. I really hope this problem could be solved.
Thanks
