Intel has found the bug in the TRIM firmware
 

Intel got a day of praise after launching the TRIM firmware for its G2 series of SSDs. Then a bug was discovered. It could corrupt the new 34nm drivers and render them unaccessible for the user. The firmware was removed immediately and since October 27th Intel has been working hard on a solution to the problem. It now says it has found the bug, but it hasn't found a solution to the problem.
