Title:
frequently lost connection to nvme
Status in linux package in Ubuntu:
Confirmed
Bug description:
Since before the release of Yakkety Yak, I've been having problems
with a new laptop with a Samsung nvme device: 05:00.0 Non-Volatile
memory controller: Samsung Electronics Co Ltd Device a804 (prog-if 02
[NVM Express])
For whatever reason, I sometimes (often) loose connection to the
device, causing the entire system to stop working until a powercycle
has been completed. I can go a full day without having the problem -
Just as I can have an entire night of the system just refusing to be
stable for long enough to be usable.
I've tried with official kernels and mainline kernels of 4.8 and 4.9
versions of the kernel, but all show the exact same problem at one
point or another.
I'm aware that this COULD be a hardware-related issue, but have no
real way to be certain at this point. The system is a brand new Lenovo
ThinkPad T460s.
Dmesg always shows the following few lines, in association with the
error:
kern :warn : [Nov12 03:34] nvme 0000:05:00.0: Failed status: 0xffffffff,
reset controller.
kern :warn : [ +0,017726] pci_raw_set_power_state: 40 callbacks suppressed
kern :info : [ +0,000004] nvme 0000:05:00.0: Refused to change power
