This doesn't seems to be the case: 

root@dbengine-ent-rm-01:~ # dig +short rs.dns-oarc.net txt
rst.x1008.rs.dns-oarc.net.
rst.x1968.x1008.rs.dns-oarc.net.
rst.x2454.x1968.x1008.rs.dns-oarc.net.
"74.125.47.142 DNS reply size limit is at least 2454"
"74.125.47.142 sent EDNS buffer size 4096"
"Tested at 2016-03-16 11:09:54 UTC"
root@dbengine-ent-rm-01:~ # 

Is there any "simple" way to do a EDNS query directly to a specific DNS?
Ok, I'll ask google about that :)

Hello!

I have an older Dell laptop with an SSD-drive (LITEONIT LCT-256M3S-41 =
7mm 256GB FDE SRDB). I installed 10.3-RC2 on it and then used ``tunefs =
-t enable=E2=80=99=E2=80=99 to turn trimming on for all of the =
filesystems on the drive (/, /home, and /var).

Things work, but every once in a while kernel logs the following error:

(ada0:ahcich0:0:0:0): DSM TRIM. ACB: 06 01 00 00 00 40 00 00 00 00 01 00
(ada0:ahcich0:0:0:0): CAM status: ATA Status Error
(ada0:ahcich0:0:0:0): ATA status: 51 (DRDY SERV ERR), error: 04 (ABRT )
(ada0:ahcich0:0:0:0): RES: 51 04 00 01 00 40 00 00 00 00 00
(ada0:ahcich0:0:0:0): Retrying command

Any idea, what is happening? Thanks! Yours,
-mi=
