Hi there, I’m running Arch Linux with kernel 4.2.5-1-ARCH
Since a few days, I have noticed a series of messages : « BTRFS: could not find root 8 » During boot. Besides that, the system behaves normally, and I have no clue… Here is an extract of the relevant parts of my dmesg : [ 1.515764] Btrfs loaded [ 1.516239] BTRFS: device label BOOT devid 1 transid 8557 /dev/sda8 [ 1.523135] device-mapper: uevent: version 1.0.3 … [ 20.639556] BTRFS: device label LINUX devid 1 transid 474967 /dev/dm-1 [ 20.952280] PM: Starting manual resume from disk [ 20.952291] PM: Hibernation image partition 254:2 present [ 20.952295] PM: Looking for hibernation image.
