Re: Fwd: [Bug 150021] New: kernel panic: "kernel tried to execute NX-protected page" when resuming from hibernate to disk

I am sorry, there has been parallel work between KASLR memory randomization and hibernation support. That's why hibernation was not tested, it was not supported when the feature was created. Communication will be better next time. I will work on identifying the problem and pushing a fix. Thanks
