Chris,
A search that is actually useful:
http://www.google.com/search?q=%22tag+0+cmd+0xb0+Emask+0x1+stat+0x51+err+0x4+(device+error)%22
yeilds 1-5 of 15 hits (one of which is Dan's email).  Hits on Google
for some random terms does not equal information, sorry.

Dan,
I get these errors too:

I have not had any issues, so I have just ignored them.  The little
bit of info out on the web seems to indicate the errors are benign.
The first hit on my Google search seems to indicate that it is a
problem with the drivers for nForce chipset SATA controllers.  I have
an nForce4 motherboard (Gigabyte, actually, like several posts on that
page) and an SATA II drive.  What hardware do you have?  Everything
points to this being not a real issue, so I would not worry about it.
