Same here, BETA7 did not exhibit this behaviour:
ad0: 78167MB <Maxtor 6Y080L0/YAR41BW0> [158816/16/63] at ata0-master UDMA133
acd0: FAILURE - MODE_SENSE_BIG timed out

Not tried, I'll do..

So you say that booting -v you don't see the error? I'll try this too!

Yes, that's the first thing I thought of, but it did no difference for
me too.
A bug with the same simptoms has existed ever since in 4-STABLE: the
ATA/ATAPI code is compeletely new in 5.x so I think it's not related,
but I quote the PRs for reference, who knows:
http://www.freebsd.org/cgi/query-pr.cgi?pr=i386/66368
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/36610
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/56889
(the latter has been closed, but without being fixed on 4-STABLE, and
the same thing happened to 36610. I hope this one is not beeing 'forgot'
for some months and the closed because 'This bug is old, I think it's
been fixed')
I've already declared in the past my availability to help in debugging,
but nobody cared (and the bug was never fixed): nevertheless, here I am
again.
