[Bug 625530] [NEW] TRIM is not being on Samsung UM41 SSD on Latitude 13 on Ubuntu 10.04

[Yang]

Public bug reported:

I'm running Ubuntu 10.04 and lshw shows a "SAMSUNG SSD UM41".

- my BIOS SATA settings should say AHCI (check)
- kernel .28+ supports it (using .32)
- ext4 supports it (using ext4)
- my disk manfuacturer says I support it
- hdparm -I /dev/sda should say that I'm using TRIM (fail!)

Using hdparm 9.30.
