Yes, see the bugzilla link. I noticed that we don't disable the harvester when suspending, so I wrote a patch to do that, see D53835. Apparently it's not sufficient. I suspect we have to do more and reinitialize the tpm firmware when resuming, but I don't have time right now to look further.home | help
