[Kernel-packages] [Bug 1694596] Re: LiteOn NVMe APST issue
My NVMe drive failed again yesterday. I no longer think the errors are due to the APST support. I'm starting to think it's either something in the Linux kernel 4.8.0-53 upgrade or simply a problem with the drive hardware or firmware. The time-line of the errors is shown below. Note that I never defined the "default_ps_max_latency_us" parameter to 6000. I only set it to a value of zero. Parameter "nvme_core.default_ps_max_latency_us" is not defined: 2017-04-04 Upgraded to 4.8.0-46.49 2017-04-24 Upgraded to 4.8.0-49.52 ← Adds NVMe APST support (LP: #1664602) 2017-05-01 Upgraded to 4.8.0-51.54 2017-05-16 Upgraded to 4.8.0-52.55 2017-05-25 Upgraded to 4.8.0-53.56 ← Errors on NVMe drive Parameter "nvme_core.default_ps_max_latency_us" is set to zero: 2017-05-29 Linux 4.8.0-53.56 (APST disabled) ← Running OK 2017-05-30 Linux 4.8.0-53.56 (APST disabled) ← Running OK 2017-05-31 Linux 4.8.0-53.56 (APST disabled) ← Errors on NVMe drive At this point, I switched from the Hardware Enablement (HWE) stack back to the original General Availability (GA) stack for the Linux kernel and X server on Ubuntu 16.04. 2017-05-31 Linux 4.4.0-78.90 (GA) ← Running OK so far 2017-06-01 Linux 4.4.0-78.90 (GA) ← Running OK so far I hope this change will help determine whether the errors are due to the drive itself or something in the Linux 4.8 upgrade. I guess we should close this bug report, or at least rename it.

Wait, APST shouldn't be enabled when the value is 6000. It should have the same effect as nvme_core.default_ps_max_latency_us=0. @John, can you check again? -- 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 APST 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:5 exlat:10 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

@John If 6000 doesn't work but 0 works, it means operational states PS1 and PS2 have issue. Can you try linux kernel in http://people.canonical.com/~khfeng/apst-rste-z/? @Andy Do we need to quirk off LiteOn completely, just like Toshiba? @Mario Does this also happen on Windows? -- 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 APST 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:5 exlat:10 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
