You should generally do Report Spam,at least I do that. If the email was sent from something you didn't actually subscribe, hitting unsubscribe tells the spammer that the email id is in fact genuine which will ultimately get you more spam.
http://sprunge.us/TEPU is my hardware and this bug is produced only on random reboots/resumes. Earlier, I had i915.rc6=7 in my kernel parameter, but I have removed it now. I rebooted and no issues but as I said, this issue happens on random reboots/suspend-resumes so I can never be sure.
On a different node, I am disappointed that kernel developers haven't been able to solve this bug https://bugzilla.kernel.org/show_bug.cgi?id=48721 since last 2 months. I am an avid linux fan but this drives me crazy.
