I've not had any issues with 4.11 myself (in fact, unlike 4.10, 4.11 was a rather uneventful kernel development cycle here), and haven't seen any 4.11-specific btrfs problems reported here either. Tho Chris Murphy and Hugo may know more, as they do the IRC channel as well, which I don't. So if it's a 4.11 issue, you're one of the first reports, if not /the/ first report, of it. =:^\ Which means it's /probably/ not 4.11 specific. But as I said, I don't do IRC, so if there's anything reported only there, I'd not know of it. (Not being a dev the trace doesn't mean that much to me.) -- Duncan - List replies preferred.
