Have been using the new kernel on Ubuntu 20.04 since 17th. Have tested the following scenarios
On power On battery Closed Lid Suspend from Shutdown menu Cold reboot Have not seen the crash since then. Anything else to do? Install 21.04 and the custom kernel and try 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/1927866 Title: Root filesystem becomes readonly frequenty freezing system Status in linux package in Ubuntu: Confirmed Bug description: I have a brand new Lenovo Ideapad Flex 5.14 which came with Windows 10 and I have installed Ubuntu 21.04 with dual boot. I am running into this problem where the root filesystem becomes readonly and the system freezes with a screen full of errors shown about unable to write to filesystem. I booted into a live boot usb and did fsck and e2fsck but did not see any errors there. I read online that this could be because of io errors but smartctl and fsck does not show any errors So I was wondering if this could be a bug vs a hardward issue. Please let me know if you need any further information from the system. ============================================================= ============================================================= fdisk -l /dev/nvme0n1 Disk /dev/nvme0n1: 476.94 GiB, 512110190592 bytes, 1000215216 sectors Disk model: WDC PC SN530 SDBPMPZ-512G-1101 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: E8803E28-C4F7-4FA5-9B6D-0F3CAB7027A5 Device Start End Sectors Size Type /dev/nvme0n1p1 2048 534527 532480 260M EFI System /dev/nvme0n1p2 534528 567295 32768 16M Microsoft reserved /dev/nvme0n1p3 567296 199446527 198879232 94.8G Microsoft basic data /dev/nvme0n1p4 998166528 1000214527 2048000 1000M Windows recovery environmen /dev/nvme0n1p5 199446528 203352063 3905536 1.9G Linux filesystem /dev/nvme0n1p6 203352064 219353087 16001024 7.6G Linux swap /dev/nvme0n1p7 219353088 414664703 195311616 93.1G Linux filesystem /dev/nvme0n1p8 414664704 998166527 583501824 278.2G Microsoft basic data ============================================================= ============================================================= smartctl -a /dev/nvme0 smartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.11.0-16-generic] (local build) Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Number: WDC PC SN530 SDBPMPZ-512G-1101 Serial Number: 205135806243 Firmware Version: 21160001 PCI Vendor/Subsystem ID: 0x15b7 IEEE OUI Identifier: 0x001b44 Total NVM Capacity: 512,110,190,592 [512 GB] Unallocated NVM Capacity: 0 Controller ID: 1 NVMe Version: 1.4 Number of Namespaces: 1 Namespace 1 Size/Capacity: 512,110,190,592 [512 GB] Namespace 1 Formatted LBA Size: 512 Namespace 1 IEEE EUI-64: 001b44 8b484daff7 Local Time is: Sun May 9 12:45:05 2021 EDT Firmware Updates (0x14): 2 Slots, no Reset required Optional Admin Commands (0x0017): Security Format Frmw_DL Self_Test Optional NVM Commands (0x005f): Comp Wr_Unc DS_Mngmt Wr_Zero Sav/Sel_Feat Timestmp Log Page Attributes (0x1e): Cmd_Eff_Lg Ext_Get_Lg Telmtry_Lg Pers_Ev_Lg Maximum Data Transfer Size: 128 Pages Warning Comp.
