First of all, please don't paste kernel log in-line and don't attach them as
tar.gz either unless the file is really big.  Attach them as separate
text/plain files.

It definitely looks like hardware problem to me.  You're trying to use wd
raptor 15k rpm drive, right?  I don't know your setup but it could be that the
enclosure you're using isn't upto the task power-wise.  The FLUSH_CACHE failure
combined with PHY going down is also indicative of power problems.  Can you
please do the followings?

1. Boot and run "smartctl -a" on the hard drive.
2. Trigger the problem.
3. Reset the computer but don't power cycle the enclosure.
4. Run "smartctl -a" on the drive again.

Post the two outputs from the smartctl.

Thanks.
