No, you aren't. This is a terrible bug report, and you seem to have sent several with the same defects. First, read: https://blog.regehr.org/archives/2037 Then, specifically to reporting a kernel bug *LOOK AT HOW OTHER PEOPLE DO IT*. Your email includes lots of stuff that is of no help and doesn't include the most important thing -- the kernel logs from around the time of the failure. > ### Affected Files > The affected files, as obtained from the VM log, are listed below.
