I tried to re-create the scenario that causes it to crash but have been unsuccessful so far. It crashed a few minutes back. Even now I am not too sure what exactly causes it to crash. So far what I have seen is that (i.e. after the re-install) the crashes have happened after I resume the system from sleep / suspend and login and start doing something. Still not been able to replicate this exactly though. I wish there was some way we could capture more logging. Keep a USB drive mounted and use that for /var/log?
I am going to go ahead and install the updated kernel now. -- 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.
