Thanks for the update, Ming. It looks like the .deb for my test kernel got
corrupt:
dpkg-deb (subprocess): short read on buffer copy for failed to write
to pipe in copy
I'll build the kernel again, and re-post it.

This bug hit me yesterday on 3.2.0-17.27 on my Lenovo T420. Will try the test

Not sure how reliable the reproducer is, seems to happen occasionally when

Unfortunately I've only seen it a couple of times, quite unpredictably,
despite using USB storage fairly frequently. Even if I were running the
kernel I'd be unable to assert that the problem was fixed with any
confidence.
It looks like the patch isn't yet in Linus's tree, but there was some

I have reverted back to 11.10 from 12.04 just because of some stability

I would like to perform a bisect to identify the commit that caused this
regression.
Does someone affected by this bug have a consistent way to reproduce the
oops?

Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during
any development cycle it is impossible for us to review them all.

further testing. This is
