I have attached the output of smartctl -d sat -a /dev/da0. I didn't yet
run a SMART long test for the simple reason that the disk is going into
sleep mode and interrupts it. Haven't bothered to keep it alive for a
long test but I might just do that.
Although, I doubt it's a disk failure, since I do backups on it without
problems by using FreeBSD 7.3, on the same space where FreeBSD 8.x
fails. And I am talking about over 150GB of data in one run, while
8.2-RC2 crashes after 5-10GB. I have experienced disk failure in the
past, on SATA, and a few read/write errors never caused a system lockup.
My feeling is that enough traffic on USB causes the problem, and that
this problem is only present in the new USB stack.
Unfortunately downgrading to 7.x is not an option because there are
things that won't work on this notebook.

Claudiu.
