Hi Scott,

This is an openSUSE bug, so you'll probably get more help there. I
added a CC: for that, and you can look here as well:
http://en.opensuse.org/openSUSE:Submitting_bug_reports

Is this easy to reproduce? Do you know whether the same thing happens
with an upstream kernel, e.g., v3.8 or v3.9-rc7? If it turns out that
this bug still exists in the upstream kernel, Zhang will probably be
interested in it.

It isn't easy to simulate. It only happened to me one. I'll file with the OpenSUSE guys and see what they say. I don't know if it happens with the upstream kernels. Thanks. -
