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
