Can somebody help me understand what my dmesg is saying. I have a 1.2 and
a 1.6 gig drive mirrored and upon boot up I get some strange messages. I
have copied the whole thing at the end but the interesting parts are
below. It appears to be having trouble with my hdd, dma timeout. Any
suggestions? Is my HD going bad? Is this a software error? or a user
error?(probably ;)

Thanks
