Comment 11 for bug 2043841

I previously verified that the test program hangs when 6.5.0-1011-azure is installed.
I have been testing with 6.5.0-1012-azure from the Canonical Kernel PPA for a while with no issues.
I upgraded to 6.5.0-1013-azure just now and the test program still passes.

The test program does not hang when running with 6.5.0-1012-azure.
