forwarded 704885 https://bugzilla.kernel.org/show_bug.cgi/?id=14733
# from upstream: "use last 3.8.5 vanilla kernel compiled myself and
# this bug exist".  Approximating:
found 704885 linux/3.8.5-1~experimental.1
# from the report: "The same behaviour happens with the kernel of the
# current stable release (Squeeze)".  Guessing:
found 704885 linux-2.6/2.6.32-48squeeze1

Thanks much for this.  If I have any more questions, I'll
ask them upstream.
