Problem Description:
more than half of the time when my laptop wakes up from sleep/hybernation what is by default root FS is RO and I think it fails to wake storage stack at all. So expected behaviour is application with error and limited functionality until hard reboot. All commands return I/O errors
Input/Output errors are often a sign of failing hardware. Have you done a check or done a check of the root filesystem partition using fsck? You can read through the page at the link below for suggestions/methods of doing a hardware check.
What does ‘storage stack’ mean? Are you referring to other partitions on the same drive, partitions on another drive and what filesystem type is on them?
Boot to Ubuntu live USB/CD and run a full fsck on the internal partitions (Unmounted). Might just be a failing disk.
Make sure your data backups are good
Hi and thank you for the kind response. I mean something is off with waking up nvmes I got on the laptop. Will do check with live USB stick but I think it is way laptop goes to sleep and wakes up that is causing the problem.
Did so and both NVMes reported with healthy FS but when I did benchmark on 1 of them running xfs it stopped reporting. Soo switched it to ext4, rebooted and now everything is looking great.
