It was reproducible when I reported it, but not anymore now. I couldn't stay in a state where I was getting hangs and corruption. I had problems with btrfs-delalloc- taking most of the CPU and deadlocking the machine for minutes or even over half an hour. I'm pretty sure it was related to the fact that I only had 10GB free on my partition (including lots of snapshots). Now that I'm back to >40GB free, I haven't had the problem come back. How about these I reported: [102231.845170] btrfs no csum found for inode 3910562 start 0 [102231.855415] btrfs_readpage_end_io_hook: 26 callbacks suppressed [102231.855418] btrfs csum failed ino 3910562 off 0 csum 3145117582 private 0 [102231.999555] btrfs no csum found for inode 3910588 start 294912 [102232.009479] btrfs csum failed ino 3910588 off 294912 csum 697692408 private 0 [102232.142602] btrfs no csum found for inode 3910588 start 360448 [102232.142661] btrfs no csum found for inode 3910588 start 393216 [102232.968939] BTRFS warning (device dm-0): Aborting unused transaction.

I know I got corruption since I saw some of my files being damaged, but are they useful in any way, or not so much?
