My problem is the following: with the 3.12 kernel on every single boot (even when the computer was shut down clear) the process [btrfs-ino-cache] is preventing the successful startup of X because it's running for 6 minutes. I can see this in "iotop" and while that program runs the whole system is being blocked. After 6 minutes I restart X and everyting goes normal from that point on. My question is: is that necessary to regenerate the inode cache on every boot or is this a bug? Of course if I remove the "inode_cache" option from fstab, this phenomenon disappears. Versions: - OS: openSUSE 13.1 - Kernel: 3.12.0-6.ge7c00d8-desktop #1 SMP PREEMPT Tue Nov 12 13:09:24 UTC 2013 (e7c00d8) - Mount options: compress=lzo,space_cache,inode_cache,noatime Best regards, Ákos
