It could be. Unfortunately, with only a Bus error message it's hard to pinpoint the exact cause. It could be any of a number of hardware issues as well as a software issue. Your best bet is to start running diagnostics on your hardware and hopefully you can determine the cause. If you cannot find a hardware problem, then you could try another USB key and a clean install and see if the error continues.
PS- FreeNAS 8.2 RELEASE p3 doesn't exist ;) There's a difference between FreeNAS version and FreeBSD version. FreeNAS is built on FreeBSD version 8.2p3.
I have replaced the cables, and the stick that had the freenas installation and now it works. I am running a scrub now and it appears that some drives had some errors, but i guess i will move the files and then pray for no more.

Is it possible that the motherboard or hdd's are to blame?
