Oops :)

Everyone makes mistakes - although I'd be very surprised there are no
testers using the same SSD as mine. It's the most common mSATA drive
around here in the UK at the moment (even if it has a slightly dodgy
firmware!).

Pesky timezone differences! I was at work when you posted this patch,
but just got home and recompiled. I can confirm this works:
[    3.845109] ata5.00: disabling queued TRIM support
[    3.845112] ata5.00: ATA-9: Crucial_CT240M500SSD3, MU05, max UDMA/133

...although the patch didn't apply as a quick copy-paste job from
Gmail ...but that's an unrelated matter :)


Thanks again,
Steven.
