After wiping out my Ubuntu installation with Windows 10 Pro and running the firmware upgrade, I discovered that it was an upgrade to the version I already have (48811QD). I also tried a separate DOS firmware upgrade program that Dell sent to me by e-mail, with the same result:
Model: CX2-8B256-Q11 NVMe LITEON 256GB Current FW: 48811QD No Firmware Upgrade Needed(N01) I reinstalled Ubuntu but this time with the Hardware Enablement (HWE) kernel version 4.8.0.58.29 installed by Ubuntu 16.04.2, just to see whether the error happens again. My home directory is safe on a secondary drive this time. At this point, if the Lite-On drive fails as it did before, I guess I'll just buy the Samsung 960 EVO SSD (MZ-V6E250BW) as a replacement and see whether Dell will let me return the Lite-On Technology CX2 NVMe Series SSD (CX2-8B256) for a refund. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1694596 Title: LiteOn NVMe issue Status in linux package in Ubuntu: Confirmed Bug description: Originally reported at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184/comments/79 The user uses "nvme_core.default_ps_max_latency_us=6000" but the issue still happens. $ sudo nvme id-ctrl /dev/nvme0 NVME Identify Controller: vid : 0x14a4 ssvid : 0x1b4b sn : TW0XVRV7LOH006AJ09F1 mn : CX2-8B256-Q11 NVMe LITEON 256GB fr : 48811QD rab : 0 ieee : 002303 cmic : 0 mdts : 5 cntlid : 1 ver : 10200 rtd3r : f4240 rtd3e : f4240 oaes : 0 oacs : 0x1f acl : 3 aerl : 3 frmw : 0x14 lpa : 0x2 elpe : 63 npss : 4 avscc : 0x1 apsta : 0x1 wctemp : 358 cctemp : 368 mtfa : 50 hmpre : 0 hmmin : 0 tnvmcap : 256060514304 unvmcap : 0 rpmbs : 0 sqes : 0x66 cqes : 0x44 nn : 1 oncs : 0x1f fuses : 0 fna : 0 vwc : 0x1 awun : 255 awupf : 7 nvscc : 1 acwu : 0 sgls : 0 ps 0 : mp:8.00W operational enlat:0 exlat:0 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:- active_power:- ps 1 : mp:4.00W operational enlat:5 exlat:5 rrt:1 rrl:1 rwt:1 rwl:1 idle_power:- active_power:- ps 2 : mp:2.10W operational enlat:5 exlat:5 rrt:2 rrl:2 rwt:2 rwl:2 idle_power:- active_power:- ps 3 : mp:0.1000W non-operational enlat:5000 exlat:5000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:- active_power:- ps 4 : mp:0.0100W non-operational enlat:50000 exlat:100000 rrt:4 rrl:4 rwt:4 rwl:4 idle_power:- active_power:- To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1694596/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
