[03:46] 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] Known issue? === marga_ is now known as marga [10:45] tmus, not know to my knowledge [12:24] apw, thanks - i'll dig a little further before logging a bug
