Hi there, I'm currently having some issues with my system freezing a lot, from a few seconds up to a few minutes. I haven't figured out yet what might be causing this, however, coincidentally some btrfs notices appeared in my dmesg after I had a freeze for about 5 minutes. I'm wondering whether this is just another symptom of my system having some weird issues or whether this might actually be the cause of the freezes I've been experiencing.
