Hello
Seeing the similarity especially that we are both using similar drives (mine i( Samsung SSD 980 PRO 1TB) makes me think it might be a hardware instead of a software issue.
Anyway its interesting that it has only started recently. Different kernel possibly?
Not sure if I can attach a picture of the error messages but some of the errors are
ext4_find_entry
ext4_journal_check_start
ext4_setattr
mounting filesystem read-only
I have done a file system check and everything seems ok and the drive doesn't have any error messages and journalctl doesn't seem to log any errors (not that i can find anyway).
I will have to disable the apst but i just thought this bug might have been fixed from 2018 but maybe not.
ps my system is a desktop system not a laptop if that makes a difference.
Thanks Dan
