This is quite similar to what I saw, except I didn't get the initial error
messages cause I wasn't on console, the machine simply froze.

The medium error above is (almost) _exactly_ what I get.

Could all the various symptoms above be the same as my problem??  Does this
tell us anything??

How can I verify that this isn't a hardware problem??

I'm going to try some new kernels this weekend and will probably be
reformatting and running a bunch of tests on the drive.

Thanks for the help
