Dear list,
I refer to this bug report:
I have exactly the same situation at boot, and this didn't happend before.
Form my kernel.log:

The bug report is about lvm, and your email appears to be about btrfs... Seems some info is missing. As to the bug report, it was just assigned to me, so I will sort it or tonight (I hope). Tom transaction_kthread+0x235/0x2b0 [btrfs]

Is it really a bug, or did I miss something or did something wrong?
TY for any advise.
