I went ahead and applied the nvme_core.default_ps_max_latency_us=0
kernel parameter to grub default yesterday (Based on this issue reported
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184)
However, I just ran into the freeze again. System was unattended for a
while and I see the login screen with all the icons blanked out.

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.
