My understanding of the problem is far from complete - I'm just attempting
to cook up some testable hypotheses to close in on the core of the
problem. I rely on the true experts to correct me if I'm saying something
totally stupid.

OK, there goes the 'its OK from kernel space' hypothesis. But it's still
only happening with the 3400 IDE, and it's not happening with kernels
prior to 2.2.15?
New hypothesis: generic too short timeout - please increase timeout to
5000 in wait_for_ready.
