Hello
I'm using a recently pulled stable checkout on Gentoo i386 with kernel
2.6.24 and I get this message:

Steps I took leading up to this message was:
Create a new FS on an ordinary block device: mkfs.btrfs /dev/sdb5
Mount it without any options: mount /dev/sdb5 /mnt/temp-test
Place a .torrent file on the FS and start download using the ctorrent
bittorrent client.
The message occurred soon after and there was plenty of space left on the FS.
The FS now appears to be in an inconsistent state.

I got a similar message yesterday using plain 0.15 without any
hotfixes. The message occurred when I was unrar:ing files on the FS.
Both messages show crc errors but I don't think there is anything
wrong with the disk.
