RE: [Bug 1678184] Re: APST quirk needed for Samsung 512GB NVMe drive
Hi, Unfortunately I do not work in this area in Samsung although I have tried in the past to try to find the right contacts (not consistently successful) Judy. -Original Message- From: boun...@canonical.com [mailto:boun...@canonical.com] On Behalf Of Ian Ozsvald Sent: Tuesday, November 20, 2018 3:39 AM To: Judy Brock Subject: [Bug 1678184] Re: APST quirk needed for Samsung 512GB NVMe drive I'd like to follow-up on this bug - it affects me using kernel 4.19.0 on a Dell XPS 9550 with a 1TB Samsung drive. Details below. Do I need to open a new bug as I've got a 1TB drive and this bug report was opened for a 512GB drive? $ uname -a Linux ian-XPS-15-9550 4.19.0-041900-generic #201810221809 SMP Mon Oct 22 22:11:45 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux $ cat /proc/cmdline BOOT_IMAGE=/vmlinuz-4.19.0-041900-generic root=/dev/mapper/mint--vg-root ro quiet splash vt.handoff=1 $ sudo nvme list Node SN Model Namespace Usage Format FW Rev - -- /dev/nvme0n1 S2FZNYAG801690 PM951 NVMe SAMSUNG 1024GB 1 314.10 GB / 1.02 TB512 B + 0 B BXV76D0Q A few weeks back I reformatted my machine due to Dropbox's requirement to drop encrypted home folders (I went for full-disk encryption). I'm using Linux Mint 19.0. I used to run kernel 4.9.91, I had to stick to that in my previous machine's Mint installation as >4.9.91 had boot issues (e.g. missing firmware for my wifi) and going 4.10+ caused other issues including, from memory, strange disk issues that I didn't track down along with occasional GPU+second screen issues. I was keen to upgrade to 4.10+ but sticking to 4.9.91 gave me a stable machine. I'm keen to push on now that I'm running on a fresh installation. Having installed Mint 19.0 and upgraded to 4.19.0 I was happy that everything worked...until left idle for a while when I got similar errors to the ones noted here: Oct 31 11:33:04 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null) Oct 31 11:33:04 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): re-mounted. Opts: errors=remount-ro Oct 31 11:33:05 ian-XPS-15-9550 kernel: EXT4-fs (nvme0n1p1): mounted filesystem with ordered data mode. Opts: (null) Oct 31 15:09:44 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null) Oct 31 15:09:44 ian-XPS-15-9550 kernel: EXT4-fs (dm-1): re-mounted. Opts: errors=remount-ro Oct 31 15:09:44 ian-XPS-15-9550 kernel: EXT4-fs (nvme0n1p1): mounted filesystem with ordered data mode. Opts: (null) After this state the machine would be unusable due to a read-only filesystem. So far I've only exprerimented with disabling APSTE (using: `sudo nvme set-feature -f 0x0c -v=0 /dev/nvme0`) - if I do this after every awaken from suspend then I'm able to use the laptop for over a week without issues with many suspended sessions. If I forget to disable APSTE after awakening from suspend then I lose the hard-drive to a read-only state in 1-2 hours depending on usage. I'm going to start experimenting with adding the grub boot parameter to try different values starting with `nvme_core.default_ps_max_latency_us=250`. I figured opening up this report and taking guidance on what you'd need and whether I needed a new bug report would get the ball rolling. Much obliged! Ian. Note that the following command was run after I disabled APSTE, I'm not sure if the results vary before/after settting APSTE, I can re-run it if that's useful after a fresh boot: $ sudo nvme id-ctrl /dev/nvme0 NVME Identify Controller: vid : 0x144d ssvid : 0x144d sn : S2FZNYAG801690 mn : PM951 NVMe SAMSUNG 1024GB fr : BXV76D0Q rab : 2 ieee: 002538 cmic: 0 mdts: 5 cntlid : 1 ver : 0 rtd3r : 0 rtd3e : 0 oaes: 0 ctratt : 0 oacs: 0x17 acl : 7 aerl: 3 frmw: 0x6 lpa : 0 elpe: 63 npss: 4 avscc : 0x1 apsta : 0x1 wctemp : 0 cctemp : 0 mtfa: 0 hmpre : 0 hmmin : 0 tnvmcap : 0 unvmcap : 0 rpmbs : 0 edstt : 35 dsto: 0 fwug: 0 kas : 0 hctma : 0 mntmt : 0 mxtmt : 0 sanicap : 0 hmminds : 0 hmmaxd : 0 sqes: 0x66 cqes: 0x44 maxcmd : 0 nn : 1 oncs: 0x1f fuses : 0 fna : 0 vwc : 0x1 awun: 255 awupf : 0 nvscc : 1 acwu: 0 sgls: 0 subnqn : ioccsz : 0 iorcsz : 0 icdoff : 0 ctrattr : 0 msdbd : 0 ps0 : mp:6.00W operational enlat:5 exlat:5 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:- active_power:- ps1 : mp:4.20W operational enlat:30 exlat:30 rrt:1 rrl:1 rwt:1 rwl:1 idle_power:- active_power:- ps2 : mp:3.10W operational enlat:100 exlat:100 rrt:2 rrl:2 rwt:2 rwl:2 idle_power:- active_power:- ps3 : mp:0.0700W

APST quirk needed for Samsung 512GB NVMe drive
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Yakkety:
Fix Committed
Status in linux source package in Zesty:
Fix Committed
Bug description:
APST support just landed in the latest Zesty kernel (4.10.0-14.16) as
part of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664602.
That patch has a quirk for certain 256GB Samsung drives found in Dell
laptops that do not behave well when APST is enabled. I am
experiencing the same symptoms with the same model laptop except with
a 512GB Samsung. Prior to manually disabling APST the drive would die
and system would go down in flames with I/O errors within 20 to 40
minutes of boot.
