Try as I might I cannot even reproduce the problem with the original
problem kernels. I've tried all sorts (such as plugging in multiple USB
disks and killing/restarting services such as udisks) but the problem
has refused to show itself again. Originally I saw the message three
times over a two days period and two of those were within 10 seconds of
boot. I've booted the same kernel a dozen times but the error never
comes back...
