UFS Trim wont stay set

[Mike Jakubik]

Hello,

I've just installed a stable snapshot on a new machine with a SSD drive, 
after installing i booted single user mode and ran

# tunefs -t enable /dev/ada0p2
tunefs: issue TRIM to the disk set

Great, back to multiuser mode, i check the partition

# tunefs -p /dev/ada0p2
tunefs: POSIX.1e ACLs: (-a)                                disabled
tunefs: NFSv4 ACLs: (-N)                                   disabled
tunefs: MAC multilabel: (-l)                               disabled
tunefs: soft updates: (-n)                                 enabled
tunefs: soft update journaling: (-j)                       enabled
tunefs: gjournal: (-J)                                     disabled
tunefs: trim: (-t)                                         disabled

What the heck.. did i miss something? Back to single user mode and

# tunefs -t enable /dev/ada0p2
tunefs: issue TRIM to the disk remains unchanged as enabled

I check again in multiuser mode and it says disabled, any ideas what is 
going on here?

Thanks.
