[03:46] <tmus> I'm intermittently seeing "Buffer I/O error on device nvme0n1p2, logical block xxxxx" in dmesg, followed up by system meltdown (no access to storage at all). This is a Samsung NVMe device in a new Skylake Thinkpad. Poweroff/Poweroff brings the system back until the next time, which could be days or just minutes. Linux 4.9-rc1 (Ubuntu mainline packages) but seen on the normal Ubuntu 16.10 kernels as well.
[03:46] <tmus> Known issue?
[10:45] <apw> tmus, not know to my knowledge
[12:24] <tmus> apw, thanks - i'll dig a little further before logging a bug
