current & V5 crashes with non-raw sata reads



Hi all,
is this worth a PR?
(or where could I start searching for the problem?)

I get: a crash if I try to read bigger blocks (~1m or bigger) from a
sata drive on an asus m4a78-vm mobo.
(I'd say buffer overrun or similar)
works fine for ata and raw sata disks.
