I didn't change pattern of work - laptop is always on, same daily job, no load at night, no hibernating. I'm on Arch Linux and do upgrade every weekend, more or less regularly. First time I had this problem was ~2022-06-15, at that time I was probably on kernel 5.18.3 or 5.18.4. I had it on 5.18.6, see #25. After next upgrade and up to now, kernel 5.18.13, I did not had this problem. This brings the hypothesis: may be the source of the problem is not (directly) in f2fs, but in the other part of the kernel, and kernel upgrades affect f2fs in a negative way? Kind of "feature interaction". Next question is: what was changed in the kernel around 5.18.3 or 5.18.4 that so dramatically affects f2fs? -- You may reply to this email to add a comment.
