Public bug reported: Hi all, This one is similar to #1805816 and #1678184 (one was fixed, other closed).
Symptoms: During regular use, system starts failing after 10m - 1hr after start. Icons start disappearing, writing to disk fails. In-memory operations still work for a while (switching windows, streaming video calls, typing). After some time the entire system crashes, with a Black Screen Of Death constantly looping: --------------------------- EXT4-fs error (device nvme0n1p5) ext4_find_entry:1455: inode #4594258: comm gmain: reading directory lblock 0 [... same repeats for 8 times on average] systemd-journald[439]: Failed to write entry (9 items, 270 bytes), ignoring: Read-only file system [... repeats for 10 times on average] --------------------------- Probable causes: Updated both kernel and BIOS 2 days ago. Unable to determine, which one caused the change. Don't know how to determine which kernel and bios I was running before the update. Looks like APST issue, based on info from web and previous bug reports. Verification: Created a rudimentary bash script, writing to a file in a loop, incrementing timeout between two consecutive writes each time. Ran script using: - different nvme_core.default_ps_max_latency_us settings in GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=[0|200|5500]" - regular boot mode - logged in to account - on battery power With default_ps_max_latency_us NOT SET: writing FAILS between 57 and 70 seconds timeout between writes With default_ps_max_latency_us=5500: no write failure during 1hrs run With default_ps_max_latency_us=200: no write failure during 30m run With latency 0: no write failure during 10m run This suggests an APST issue. Machine: Lenovo Thinkpad T570 Disk: SAMSUNG MZVLB512HAJQ-000L7 512 GB (512110190592 bytes) Firmware: 3L2QEXA7 Serial#: S3TNNE0K119126 System: OS 1: Ubuntu 18.04.5 LTS Kernel: 4.15.0-122-generic #124-Ubuntu SMP Thu Oct 15 13:03:05 UTC 2020 x86_64 OS 2: Windows 7 (on a separate partition on same disk, dualbooted with grub). Actions taken: Successfully checked the partitions for errors by running "Check partition" and "Repair partition" in Disks utility in Ubuntu, running from a bootable USB. Starting in "recovery mode" yields an error (among other suspicious behavior): -------------------- sd 0:0:0:0: Attached scsi generic sg0 type 0 sd 0:0:0:0: [sda] Attached SCSI removable Disk input: TPPS/2 IBM TrackPoint as /devices/platform/18042/serio1/serio2/input/input .... nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0x10 nvme 0000:40:00.0: enabling device (0000 -> 0002) nvme nvme0: Removing after probe failure status: -19 nvme0n1: detected capacity change from 512110190592 to 0 print_req_error: I/O error, dev nvme0n1, sector 1000215040 nvme nvme0: failed to set APST feature (-19) Waiting for suspend/resume device ...

[repeats] -------------------- Without nvme_core.default_ps_max_latency_us set: writing fails between cca. 57 - 70, on battery. With nvme_core.default_ps_max_latency_us=5500: FIXES THE PROBLEM. With nvme_core.default_ps_max_latency_us=200: FIXES THE PROBLEM. With nvme_core.default_ps_max_latency_us=0: FIXES THE PROBLEM. Previous behavior on same machine: Same OS, with a previous Kernel has been running perfectly fine for the last year, "on high revs" (it's a development machine). Often running on battery alone. sleep and wakeup without issues. It is running Windows 7 (dual booted) without issues. Misc info: To test different settings, did 'sudo nano /etc/default/grub' with each of these settings: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" # GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=5500" # GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=200" # GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0" followed by 'sudo update-grub' and reboot.
