Hi guys,
I was playing on vmware with btrfs on complete disks /dev/sd{b,c,d,e}.
Next I decided to use partitions, so I created /dev/sd{b,c,d,e}1 and
used those, worked fine! Afterward, I mistakenly re-ran an old command
on the full disk ( mount -t btrfs -o subvol=. /dev/sdb /mnt/ ) notice
this is sdb not sdb1, and I got this spectacular kernel freeze. Let me
know if that's some bug.
