No, nothing really special there.
It's just a single drive / single filesystem (K)Ubuntu install originally,
with various test 2.6.25-rc* kernels being substituted in.
There are lots of other drives in the box for driver development,
but they have nothing to do with the ext3 root fs.
My guess would be that the 4 fast CPU cores managed to race on something.
Cheers
